Hello and Welcome! There's so much to learn around here, and the people on this forum are great. The more you learn about the pins, the better you (and she!) will become at buying them on ebay. When I first really got into pins, I found a pin on ebay that I hadn't seen before, and (ahem!) may have bid a little more than it was really worth in my excitement. I think I was bidding against another person with a similar mindset. When another of the same pin showed up on ebay a couple of months later, it went for noticeably less. Ah, well. I still love the pin! What characters or themes do you two collect?
