Avoid this site at all costs.
A quick Google brought up the best price and I unfortunately fell into their trap. Wanted to buy an FFX HD Remaster CD key to download on my PS4, what I got was a bunch of shady PSN credentials and very specific instructions to get the game downloaded, which had been blocked by Sony for an blatantly evident breach of the PSN EULA. I get that MMOGA is a meta-sales site, that little to nothing is sold by them but you'd think they'd put more effort into vetting the people that sell via the site.
I'll admit while initial contact from support was fast, they fobbed me off with the "we've contacted the seller and will get back to you" response. It's been days now in what is a very clear cut case of illegal practises by the seller. I should have been reimbursed immediately.
In short: AVOID THIS SITE AT ALL COSTS! Seriously, I'd give it a zero stars if I could.
