It depends on the number of credits bid. This auction will likely not be mailed with tracking due to it being a low value item. But I do document all my shipments by time-stamped photos and retain receipts when applicable.
Hi there! If someone asked you to do a GIN for these, about how many credits would you ask for? I have 137 of these to auction off and I don't have a good sense how much they're worth (by GIN) since I don't usually buy/sell these. Thanks for any advice you can offer. :-)
