"I bought a 12-pack of 'Dust Off' 10 oz canned air, air duster (to clean computers) from Southern Hills Computer. This stuff usually goes for like $7-$8 a can, but I got the 12 pack box for a total of $43.88 with free shipping-- that's $3.66 each.
I ordered this on December 26, 2008 and received it on Jan 6th, 2009-- which is pretty darn good for the Holiday Season in my book, especially with free shipping!
All in all, I found myself quite pleased with Southern Hills Computer and have no problem at all highly recommending them."
