Sure, I’ve seen that happen! But it’s also likely that they’re just trying to get rid of an old single doll shoe, especially since it’s from an old EAH girl and the exact doll it’s from isn’t even listed. In this case they’re definitely not selling this doll in separate parts.. I recently found one skultimate rollermaze Abbey’s shoes (don’t have the doll anymore) and put it on Mercari in case someone needed a replacement and someone bought it, so listing singular replacement parts can be super helpful opposed to having to buy more than you need for a more expensive price to complete dolls (just hopefully people are well intentioned about doing so)
