How many sales does one need to perform in order to be able to request and obtain a personal discount code on Gameflip?
I think is not only about sales but how many listing you have active as well. Ofc, you must be verified seller and later is giving to the most active sellers on website.
You cannot request one. It’s given by Gameflip.
As Pawel wrote ^^. Just to add on, some other factors would be the cost of the listings your selling. Of course, the listings must be sold and at a medium/large quantity depending on the cost of your listings.
