Online stores allow you to save time spent by a person searching for a particular product and driving through shops.

Introduction
Electronic commerce is a business in which information technology is used to increase sales, business efficiency and provide a basis for new products and services. Through its activities, each company communicates with many other entities: it may be private or corporate clients, business partners, suppliers. When communicating with each other, these entities exchange various types of information: they inform themselves about their products and services, negotiate the terms of transactions, exchange documents, transmit and accept orders for goods, complain about inappropriate services, distribute press releases, etc. The flow of information is also carried out among all of these entities: managers and subordinates communicate with the company, marketing specialists talk about vendors and product managers. Internet popularity has provided many new opportunities for business. Accelerated and simplified communication and unimagined technical capabilities have enabled smart entrepreneurs to create advertisements, stores, and other promising items on their own, on the Internet. Moreover, the growing number of Internet users has increased the volume and profitability of the use of commerce and services.

Ritter, J. B. (1992)
International electronic commerce is not simply defined by the absence of paper documents. Indeed, though an important objective of many commercial and administrative users is the elimination of paper, most users will also admit that current implementation efforts remain heavily inter-dependent upon the continued use of paper documents. Ngai, E., W. T. and Wat, F. K. T. (2002) , There is a growing interest in the use of electronic commerce (EC) as a means to perform business transactions.

E-commerce Advantages and Disadvantages
Electronic commerce is a tool for promoting new forms and dimensions of business. After all, you can sell your online store seven days a week, 24 hours a day, and you do not need any special premises, sellers, complicated accounting systems or stores in each country. Your online store is accessible, visible and visited everywhere and always, and your customer does not even need to leave home to buy a product that he likes, he only has to click on the "buy" button and the courier will deliver his desired item directly to his home (see-marketing.lt, accessed 2017). E-commerce offers the user the opportunity at any time, regardless of where it is located (as long as the user has access to the Internet) information on goods and services, as well as purchasing them. This removes the barriers associated with time and space constraints when acquiring goods or services. The user has the electronic space the ability to compare offers from different traders regarding price, quality aspect, and assessment seller's credibility. The user can personalize his purchase and keep himself from subjective criteria for determining the product's choice, such as seller's persuasion, alleged discounts shares. The ability to be cheated -Your money security depends on your vigilance. So before submitting your personal information, check that the online store is trusted. When you buy online, you risk not getting or getting the same as the one shown in the photo. Information details and recommendations -Detailed information is provided for each item in the e-shop. Here you can find product reviews and recommendations.
It is easy to make a mistake on the price -Keep in mind that the product will have to pay more than specified.
Lower prices and better choices -Online sellers do not have to pay rent or wages to employees. It is convenient for you to compare prices for the same product in different e-shops in a short period.
Lack of privacy -Some online stores even unsolicited send you emails about various stocks and new items. On the one hand, this may seem useful, but on the other hand, it is a way to get you more money.
Starting an e-business requires less investment than traditional commerce When ordering a product online, it often takes a long time before it is delivered, and shipping charges sometimes exceed the price of the item, especially if the product is ordered from abroad. Repaying your online purchase may be more difficult than buying a traditional store A wider circle of consumers is attracted (disabled, foreign clients) More varied and more convenient supply of goods and services Often money will not be refunded for shipping, and in some cases, it will even have to cover the cost of returning the product itself. Also, when shopping online, it is important to make sure the website is trusted, and your credit card or online banking data will be protected. Finally, shopping online will not be able to see the goods (like clothes).
Comfortable billing (bank charges, bank link integration).
The main advantage of e-commerce is to provide its current and potential customer with all information about the product, to offer to order and pay for it online, at any time of the day and anywhere, on the Internet, advice on matters of concern (Misevičiūtė, 2001).
Electronic commerce also has some failures. Studies have shown that 35% of expensive goods sold in virtual stores are pirated. Investigations have also shown buyers a lot of confidence (Misevičiūtė, 2001).

Statistical Data on E-commerce in Lithuania
In the EU Member States, e-commerce in 2016 accounted for 9.4% of all retail sales. Compared to previous years, e-commerce grew by about 11%, while trading areas shrank by about 1.5%. Still more significant changes are recorded in those countries where e-commerce is already a relatively significant part of all retail sales. One such country is the United Kingdom. In this country's retail market, the share of online shopping is about 17% and is proliferating. At that time, the area of trade fell by more than 4% over the past year (Sagatauskas, A., 2018) In Lithuania, the share of online shopping is still a relatively small part of all retail trade -in 2016 it was about 3.5%. A Eurobarometer survey shows that every third person in the country has been online at least once in the EU. Thus, at present, a larger proportion of Lithuanians still enjoy visiting physical stores, and the volume of online sales is too small to have a real impact on the decline of traditional retail outlets. Vilnius is worth mentioning individually, with a trade area (679 sq. M) per capita now considerably lower than in Riga or Tallinn (998 sq. M and 817 sq. M respectively). Therefore, in the future, we should still hear about the projects of new shopping centres in the capital of Lithuania.
According to the data of the EU statistical agency Eurostat, the indicators related to e-commerce have rapidly risen in Lithuania:

Conclusion
Electronic commerce is usually defined as the automation of routine business procedures and operations and the transfer to virtual space. This process greatly increases business efficiency and simplifies everyday routine work. Up to now, it has been assumed that most e-commerce transactions are conducted across the globe, but recent research has shown that businesses are moving fast between local companies. Many businesses keep internet and e-commerce in a more convenient way to market their products on the local market (news.lt, accessed 2018). Most online retailers are cheaper than the same products offered in regular stores. This is the main reason why today's online stores are gaining market share. Some online stores have exceptional conditions where you do not have to pay for delivery at home for a certain amount. When trading online, less time is spent on paperwork, as in the e-commerce sales, as reports are automated. It is convenient for small businesses to go online because they can easily compete with bigger ones. Also, online sales are cost-saving -there is no need to rent an outlet to the store, and warehousing is not always necessary. It is much easier to access foreign markets on the Internet. The biggest shortage of online stores is that it is not possible to see a product before buying it (tv3.lt, accessed 2018).
