That affiliate thing wasn't there when I signed up, or I don't recall it at all, I wouldn't think you'd have to sign up with their affiliates to sign up with Gaminglagoon though. Custom order is where you can order things that are on the "subject" of gaming, such as something that isn't on their website from anywhere, unlike the limit of Amazon only for PrizeRebel.
I also imagine if you used a cell # as your main number, that you shouldn't receive any texts. Just don't signup for the cell phone service offers they have, or you'll likely get more than just texts.
I like Amazon though lol. So if I wanted GH3 and Amazon had it I would order from them using points? How much points = GH3 lol
