The codes have always worked for me and they've been delivered in seconds, which is more than I can say for Sony's own built-in payment methods which like to lock you out arbitrarily.
I love that I can get these on this website. My son will do chores for an "allowance", but all he wants in payment is V-Bucks for Fortnite.
No complications here... I used it this great website, received the code instantly, went to PSN and entered the code, and I was in business.
I was hesitant to get because I saw so many websites that said their code was invalid, didn't work, or took an exceedingly long time. I decided to take the gamble anyway and get a $10 one here. I got and it showed up immediately and I was able to redeem that took me to the PlayStation site directly. I logged in and redeemed it and it was all done. I was on my PlayStation making a purchase moments later. So, it worked great for me!
This was my first time getting a Playstation store gift card and I was worried that something would go wrong. But, to my surprise, everything worked out great! A minute or so after getting the card, I received with the code. I proceeded to my Playstation account and entered the code, and voila, the money appeared in my account. Easy peasy. I will be getting more of these cards in every week. Thanks, PSNCodeExploit.
