I also tried to earn a little extra money using the described method, but it took too much of my time, so to avoid losing my job, I had to give up on that idea. Since I buy a lot online, I can say that it helps me save. I used to browse many stores, but now I only choose those that offer cashback, and honestly, I mainly shop on Ali. The cashback returns can vary, but I have encountered the promised 15 percent. I didn't have any problems with withdrawing funds at all.
