I heard about the cache-back system even when it was popular in the West, but I still did not understand how it works, when I saw a video about letyshops.ru it immediately became clear how it works, and with an understanding of how it works, there was a desire to use it. I would also like to note the browser extension, which is very convenient, I have not seen any analogues to it.
