Good day, Sergey!
Thank you for your feedback. Unfortunately, indeed, some reservation services reserve the right to change the cost of their services depending on the source of the transition.
We were previously contacted by users with a similar problem on other similar services, for our part, we checked this information and the services were either disabled or the relevant information was posted on the service page. Unfortunately, it was not previously noticed that when you go to the Kupibilet website, the price changes.
Believe me, we in no way influence the pricing policy of stores and services with which we cooperate. In order not to mislead our users, work with the Kupibilet service was discontinued.
We really want our users to make only profitable purchases with our service. Thank you very much for reporting the problem. You help us get better!
If you have any questions or suggestions regarding the work of our service, please contact us, we are always happy. Have a nice day!
Respectfully,
LetyShops.ru team
