What card sellers struggle with
Box price chasing
2024 Bowman Chrome MSRP is $400, hobby retail can hit $700+. Slot pricing has to cover cost. Most sellers running breaks at MSRP are losing on the broken-out value.
PSA / SGC turnaround
30-90 day grading lead times. Cash flow gets bumpy if you over-stock raw inventory. Plan for working capital coverage.
Per-show profit visibility
Whatnot shows gross sales per show but doesn't know your hobby box cost. A $1,200 show can be $200 profit or -$50 depending on what you paid.
Tax season chaos
1099-K covers gross. You need fee deductions, COGS, refunds, and shipping costs categorized for Schedule C. Most sellers patch this together in spreadsheets.
