What is the name of your shop. Because you don't have them on your profile.

Did you recently price them? It might be that the cache hasn't updated.

But shouldn't she show up if she is among the cheapest?

that's actually exactly how it already works :D

the problem here was actually that there were a lot of low priced vesnali coins in shops that had zero coins, because the price records weren't being correctly deleted when the last of the item was bought from a shop (likely due to spam buying). which has been fixed.

Please see above! Thank you for your report!
