A PSA submission shop is typically a local business that helps customers send cards to PSA or another grading company. The shop may create the order, package cards, combine shipments, collect payment, and receive returns. It does not mean PSA employees are grading cards behind the counter. Use the PSA grading and submission shop directory to find possible drop-off points, then call because submission partners, accepted service levels, and intake days can change.
Before handing over cards, ask what company receives the submission, whose account is used, how declared value is chosen, what insurance applies, and what paperwork proves the shop has your cards. The PSA submission through a local shop guide explains the workflow in more detail. A good shop will identify each card on a receipt, explain timelines as estimates, and tell you how status updates are handled. Avoid any intake that depends only on a handshake for valuable cards.
