I have done so many mail in rebates and have gotten all of them (i'd say I've done over 30 in the past 2 years, no exaggeration). you are missing out on a lot of great deals by choosing to avoid MIRs.
i paid $51 final, after tax shipping everything for my GTX 460 (768) brand new...... needless to say that is a KILLER deal. there were 3 rebates for it that brought it down that low.... you're missing out.
by the way, a bit off topic but also relevant... i see u have a 4850. i do too, i got mine for $22 final after tax and ship and rebate. again, you're missing out bro and paying too much by avoiding MIRs.
