I would like to know when there will be credits of 2 dollars for a five or ten dollars in purchase ?
If you’re talking about them adding $2 credits to your account as a promotion without asking you to buy anything, then they rarely do that.
If you’re talking about coupon codes for $5 max, then they do this pretty much on a weekly basis.
If you mean those promotions that say buy something for X dollars and you get extra credits added to your account, then they also do this frequently. You just have to wait like the rest of us because they can’t tell you when they are going to happen
