We have a 15 day refund policy on sealed or unused new products. The return must be accompanied by a receipt from our store. If a receipt cannot be provided store credit will be provided at the lowest sale price within the past 6 months.

Trading card game items such as booster packs or sealed boxes are not returnable unless they have not left our physical building. 

Any and all tcg boxes are not guaranteed to be in perfect condition. All items we carry will have intact (but perhaps not perfect) shrink wrap, if originally produced with shrink wrap. If you are purchasing an item for a sealed collection or expect perfection, please do not shop with us. We will not accept your return and we don't want to deal with sending dozens of pictures so that you can inspect our products via email.

If an item is shipped and arrives damaged, an insurance claim will be filed and reimbursement will be passed on once the claim has been fulfilled 


Any products that are bought used can only be returned if they are found to be defective or not as described when purchased. These items may be returned, but only before leaving the store. It is recommended that buyers inspect any used games thoroughly before purchasing to find anything that was potentially missed during the store's initial inspection upon acquiring the game.
