Supreme Card Shop

Supreme Card Shop is a card shop at 9122 Fletcher Pkwy in La Mesa, California, built around sealed boxes, Pokémon and sports cards, and a PSA grading desk. It is open seven days a week, buys as well as sells, and also ships orders to collectors who can't make the trip. It suits someone who wants sealed hobby product, a place to sell cards, or in-person help getting cards graded.

What's on the shelves

Pokémon is the one trading card game the store carries, and the stock leans toward sealed product: booster boxes of recent sets such as Phantasmal Flames and Destined Rivals sit at the front of the inventory. Sports cards get equal weight, with baseball, football and basketball boxes, plus soccer product such as Topps Chrome Premier League hobby boxes and MLB blaster boxes.

Beyond boxes, the store sells Slabmags, magnetic display holders made for PSA and CGC graded cards, which makes it a handy stop for anyone who has slabs to show off. Live breaks are part of the offering too, for collectors who like to buy into a box opening rather than buy the whole box.

Buying, selling and grading

The store buys cards as well as selling them, so it works for people looking to sell a collection or a few singles. It is also a PSA authenticated partner and takes grading submissions in store, which saves a trip to the post office and lets you hand a stack of cards to a person.

Hours

Weekday hours start at noon, so mornings are not an option.

Ordering from a distance

Orders are processed and shipped within 1 to 3 business days. Standard shipping typically takes 5 to 7 business days, and expedited options are available at checkout.
