I added goods in this online store, applied a secret word, a certificate. The discounts that were put to me as a new customer have made it. Then I recorded a transition to the site, because I forgot to do it right away. But this does not change the essence. After that there was an interesting trick. All discounts from your personal account were deleted, and it was already impossible to punch them again! I thought something with a browser. I tried from another - the same thing. I tried it from the phone - it's useless. I tried to create a new account, as soon as I fix the transition from LetyShops, the feeling that the Labyrinth is blocking the IP address so that the discount does not break through. Because changing the browser, rebooting, etc. does not help. I called the hotline, the operator entered my personal account and entered a secret word, the discount got through. I refresh the page, the discount disappears. OK. I tried to test my theory, I tried from the mobile Internet, there is another server. And what do you think?! That's right, the discount made it right away. That is, the Labyrinth did not already know that I had supposedly come from LetiShops. Here is such a trick! That is, the Labyrinth wants people to come from here for cashback, and ... block all discounts themselves !!! The mess is complete. As a result, I used another service with a cashback, where it is more than 3 times and there were no problems. Correctly people say, "you want to shake your nerves for the sake of three cents, to you on letishops." Hmm ...
