I'm a frequent Goodwill shopper (I think of it as a game too!), so I've found quite a few Disney items. I don't buy everything I see, but off the top of my head, I did get a very nice Mickey silhouette wooden picture frame that I used for a vacation photo, a Rock N Roller Coaster wine glass, and an Expedition Everest mug, all of which I kept for myself. I also found a vintage Flower stuffed animal that sold on Ebay for $25, and my best find was a like-new Pal Mickey that I bought for $4.99 and sold for $75 on Ebay!
I do see a ton of Disney merch while I'm thrifting, and it's hard to turn away from things sometimes. But I only have so much room.
