Here at Card Gamer, we’re big fans of TCGplayer, which we use to check on what’s hot and what’s not across just about every trading card game you can think of, as well as for getting our hands on those pesky cards that we just can’t seem to pull from our favorite booster packs.
With TCGplayer‘s Mayhem event almost here, we’re even more excited to treat ourselves to lots of new cards for our ever expanding TCG collections. That’s because, on May 16th, with Mayhem underway, you will earn 10% store credit on everything purchased from the site; unless you’re a subscriber, in which case you can earn 13%+!

If you’ve yet to use TCGplayer, this is the perfect time to sign up and buy those cards you’re looking for; perhaps you’ve been holding off on getting your hands on that sweet, but oh-so-expensive “Moonbreon“?
Note that the promotion runs for just one day only, on May 16th 2025, and you’ll also need to make sure any purchases you make are processed between 9am-11pm, ET.

TCGplayer is well known in the card gaming community as the most trusted trading card game marketplace in the world, and that’s in part due to the fact that anything purchased from the site is sold by either a local game store, or a fellow TCG fan such as yourself. Many of the team here at Card Gamer have been regular users of TCGplayer for several years, and it’s definitely our go-to online store for buying and selling cards.
Maybe you’ve always wanted a Mox Sapphire or a Showcase card from Star Wars Unlimited? If so, now’s the time to pounce: set your alarm for 9am ET on the 16th of May, and head over to TCGplayer to take advantage of their Mayhem promotion to bag yourself a bargain!
