I often place orders on AliExpress and regularly share my impressions of the products on my blog. This service has been a real find for me: as a blogger, I earn a small amount from purchases made through my links, and as a buyer, I benefit from cashback. Although I can't say it's my main source of income :) I receive just over 8 percent of the product's cost with each purchase. For example, if I promote a cosmetics set costing around 1000 rubles, I get 80 rubles credited to my account from those who buy it. The cashback isn't very high either; I receive it after confirming the receipt of the product. While the savings are modest, it's always nice to save a little extra money. On average, I manage to withdraw about 5-6 thousand rubles a month and save around 400 rubles.
