Total Price is what a buyer actually pays: item price + shipping + marketplace fees (Mercari charges buyers a 3.6% Buyer Protection fee on the item + shipping; eBay has no buyer fee). Pinny Shop ships free on US orders over $59, adds a flat $6 below that, and charges a flat $15 to Australia and Canada. Tax is not included. eBay shipping is what that country's eBay quotes, for the currency you pick: to Seattle, WA for USD, to Melbourne, VIC for AUD, to Vancouver, BC for CAD. When a listing is not offered in that country, its total is shown to another, and says so. The flags on a listing are the countries it is offered in. Mercari ships within the US only. Shipping may differ for other locations. A listing with no shipping figure is one we have not been able to retrieve yet.
Sold is the marketplace's own record: Mercari's sold listings, and eBay's count of units sold on a listing we tracked. Probably sold is inferred: an eBay listing that ended before we could ask eBay about it, and disappeared and stayed gone — except one that ended exactly at the end of a listing period (7 days, or a multiple of 30), which most likely just was not relisted — or a drop in Pinny Shop's stock, at that day's price.
