I absolutely love DealExtreme. I have bought so much stuff from them. I bought a scope for my .22 and it's worked flawlessly. That's the only gun related thing I purchased but, I bought numerous other things I didn't need haha.
I bought a battery for my phone that is exactly the same as the original for $5. I can't tell the difference cosmetically or in actual tested output between the original and DX battery. The Sprint store charges $60 for the same battery. I also picked up some computer stuff, some random cables, a bullet lighter, and other useless gadgets from them.
