One winter morning, a work colleague noticed that in different browsers on the
Presenting Vimeo Plus page, different subscription prices are shown. He had it $ 49.95 and $ 59.95. Immediately suspicions crept in why this Vimeo so strangely puts down the cost of an annual subscription. Although on my machine all browsers showed the same amount.
After a little research, we realized that the price was saved in a cookie named 5vimeo_cart:
%7B%22item_class%22%3A%22AccountFeatures%22%2C%22user_for%22%3Anull%2C%22item_identifier%22%3A1%2C%22name%22%3A%22Vimeo+Plus%3Cimg+src%3D%27%5C%2Fassets%5C%2Fimages%5C%2Ficon_plus_tiny.png%27%5C%2F%3E%22%2C%22cost%22%3A 59.95 %7D
The reasons for such a different statement of the amounts have not been clarified. As an experiment, we decided to try to set our own value and try to buy a subscription for a year. Just for this there was a suitable card with $ 4 in the account (there was nothing to lose, it would still not be removed anymore). Change the cookie, specify the data card and voila - a year subscription for $ 0.01:

The page says that the price is $ 59.95, but according to the bank statement - $ 0.01 is written off. After that, I immediately wrote a letter to the Vimeo administration describing the problem and our atrocities.
I did not think that such a serious project will not have validation data on the server.
Ps. The post was written as much in January and was lying in the drafts. I just tried to repeat all this, probably the bug was already closed, although no one answered my letter.
