I learned about this service from the channel of one person who talks about purchases in foreign stores. To be honest, I reacted a little with distrust to this service, before that I used another service I will not advertise it, I can say for the entire time of its use I have accumulated a cashback for 1 dollar, there were a lot of orders, the whole point is that they gave cashback for small things, for goods for which there was a high price, cashback was not charged (although it should be charged). I turned to the Letyshops service and it did not disappoint - for large orders it charges cashback, everything is transparent and understandable in my personal account, after a request to withdraw money, the money came the next day. I really liked the add-on to Gooogle Chrome - now, for any store, you can find out whether cashback will be credited or not.
