TJ-Maxx has quite a few cases and they're extremely cheap. They're the Griffin cases. I've bought quite a few there.
x2 on buying one at TJ Maxx. I just bought a few today at Marshall's (A discount store similar to TJ Maxx) for $6.99-$9.99.
they are all pretty good quality. most come with a case, screen protector, and a cleaning cloth.
They also sell a ton of cheap (9.99-$19.00) car chargers, and kits that have car chargers, speakers, and a video-out cable for like $14.99.
There's a ton of decent quality accessories at a super-cheap price.
I went to the Verizon store for a case for my old ATT Curve.
Would Storm cases work?
Tj Maxx and Marshall's are owned by the same company, so you will probably see similar items...
