accidentally bought as many scrolls of wisdom as possible

somehow just spent all my gold on scrolls of wisdom when i just wanted to buy one, (not sure if i fat fingered some key while clicking on it in the shop that makes you buy max capacity).

is there anyway to refund for full price or something? i thought since buyback exists as a feature, then similarly when buying an item from a vendor you'd be able to resell it for full price if you havent left the vendor.

appreciate any help, ty <3
