Paste the board-game list you already keep. You get back the finished for-sale post: one clean line per game with its price and condition, the item count and total, bundle-discount tiers computed from that total, and the games that still have no price or no condition note.
This is a prototype, not a finished product. It is not for sale yet, and it takes no payment. If you would use it, leave your email and I will write to you when it works end to end.
