Or you can go next level like my wife and I and make your own stuff lol! I see a design I like, I recreated it in Inkscape, then use the Cricut to cut the vinyl to iron on the shirt. It's definitely saved us money in the long run (especially when a t-shirt is $25 - $40 bucks)
I've only been to Cast Connections the one time, but from what my friend was telling me it can be hit or miss. You never know what they are going to get, but I'll tell you, I also got some nice little kitchen stuff. Ice cube tray for $4...again, what it would cost in the real world. I got some magnet that they sell for $10 in the parks for 99 cents. If I was a CM, I would find out when they get shipments and hit that store up weekly...I'm sure a bunch do that.
