Mail In Rebates - why I don't purchase quite a few things on "sale". MIR's rarely if ever get processed in my personal experience (Ive received zero back in 2 years and the time spent trying to run these "savings" to ground to no fruition makes them zero value). Give me a promo code, money off immediately, Ill buy it. But anymore I just do not trust any of the vendors for PC parts to reliably process their own MIR's.
