Caps in DFW
Tanner Electronics in Carrollton is a goldmine for caps and tons of other stuff, all reasonably priced. It's like a supermarket, pick up a basket and keep up with the prices yourself. Plus, a helpful, friendly,staff . They are truly a mom and pop, but very large operation. Open on Saturdays, too. They're easy to get to--just take Valwood west from I-35. It's about a half mile..see Tannner on your right..the headquarters for The Container Store is on your left.
There is also Allied Electronics in Ft. Worth..haven't been there, but a friend says you can't see the inventory like at Tanner. You have to see the parts clerk at the counter and he steps and fetches.
There's also Alltex in far N. Dallas, you can see the inventory + help yourself, but it seems to be more PC oriented.
Hope this helps!
