MONEY: Get $50 off your $100 Best Buy purchase via MasterCard Coupon!

Best Buy and MasterCard have teamed up on a potentially incredible deal: get $50 off your next $100 or more purchase at Best Buy stores! (Must be in-store purchase.)

All you need to do is print this coupon and then bring it to a Best Buy store to make the purchase of $100 or more using a MasterCard credit card. (Prepaid cards may not work. YMMV.)

• Remember, PRINT THIS COUPON FIRST and bring it in with you!
• The combined total for the purchase should be at least $100. Note the exclusions on the coupon. Your miles may vary (YMMV) for everything on this deal.
• Make sure you are paying with your MasterCard credit card.
• Discount should be automatically applied.

This deal is currently going around like wildfire on the deals blogging community. Coupon expires January 27, 2013. I would recommend giving this a go ASAP. Check out this Slickdeals thread for more info on the results others are reporting on this deal.

Just use your favorite miles-earning MasterCard on this deal. 🙂
