Cup Locations?

I'm a Texas History teacher in the DFW area and I'm just gonna go balls to the wall crazy on Texas decor for my classroom. I wanted to get one of each of the current collectible cups, but when I went to the one on 183 in Euless, they only had the table tent design!

Can anyone point me in the right direction of stores in the area that have the other designs? I would appreciate it so much! :)
