I want to create a listing but it has a large number of variants (1991 Upper Deck Baseball is an 800-card set). I have seen several listings that will not list all variants; rather they will just have "quantity" and they instruct users to list the card numbers they want in the buyer notes of the purchase. Here are some examples:
I want to use this style so that I don't have to list all 800 variants (across 4 separate listings because you can only have 250 variants per listing), or maintain inventory in the listing description. However if a buyer requests a number of cards that is not consistent with the buyer notes (examples - they leave the buyers notes blank, or they request 5 cards and only list 2 cards in the notes), I am concerned about potential eBay defects. If I partially or fully refund the buyer in this situation because the order was not properly filled out, then eBay would count this as a defect. Is there any way I can seller protection in this situation?
I was also considering only posting quantity after a buyer contacts me prior to ordering to confirm the cards they wanted are in-stock, but that doesn't stop someone else from swooping in and creating the situation I mentioned above.
