An online shop refers to a shop that sells over the Internet. The goods can be inspected via the website of the Internet Shop. The sale is therefore not bound to any opening hours and the products can be viewed and ordered around the clock on the Internet. A disadvantage of the online shops is, of course, that the goods can be taken only after an order in view. This is not very bad for some products, but especially in the fashion industry, the articles are often tried on by customers before buying. These types of online stores have a high number of returns. The return is for online shops regulated by law and some shops do not even pay a fee.
