I do not recommend using the Aviasales + LetyShops bundle for cashback for ticket purchases. It is charged from 0.1% to 1.5%. Moreover, this is real roulette and there is no objective clear understanding of how much money will come to you and what it depends on. A simple example. I bought tickets for two flights + baggage, a day later I bought two more tickets for two of these same two flights, but cheaper (without baggage). For the second purchase (cheaper), the cashback turned out to be ... more! The support service said that LetyShops is not aware of which algorithms Aviasales uses for charging and why such strange situations occur. Perhaps they do not use any algorithms, or they themselves do not know how they work. It’s easy to get a refund of 29 rubles from 11k (also according to LetySilver) as with an ordinary purchase from Aliexpress from such a famous ticket aggregator - it’s somehow too small and pathetic. There are more interesting options. Thanks to the LetyShops team, I think it doesn’t depend on them in any way, and I think that they themselves are not happy with such cooperation with AviaSales, but for some reason they don’t have the opportunity to agree on a transparent cashback scheme, and lose such a major player do not want.
