I recently acquired a couple older Stampin Up catalogs
and was surprised to see PSX Botanicals in them!
I do believe some are willing to pay top dollar for a set if it is one they really want. Especially if it is a hard to find. I have to admit I have almost gotten carried away on ebay a time or two, and have bid more than I had planned on occassion but never to an extreme. So I know how you can get caught up in the moment.
