To test the checkout in the online store

Hello!

Need to find the bugs that prevent users to checkout in the online store and just everything associated with your order.

We need to test in all possible browsers desktop and mobile also. The main condition – need to find a bug and "fix" it, to repeat, i.e. to describe a detailed sequence of actions causes the error, what browser, etc.

Payment for found and fixed errors. I would like to hear who has the desire to take and the cost for 1 mistake found.
