i've tried pcgamesupply and all those others, offgamers were the only website that approved my in under 1 hour and i always get the codes within 10 minutes when i buy from them. in my opinion they're the best.
I used this site today. To buy a $10 UGC card.
Took about 10> minutes.
When I tried to buy from playspan.
I either had the option to buy a $8 UCG or a $20 UCG.
Like i said and ill say it again most of these other sites need confirmation calls and this site i didn't need that and i've bought 200k+ nx off them since i found the site everything approved in under 10 minutes. its great!
