I did deal like this a few years back – its one of the examples in the book —- The Frugal Factor.
$100 off 4 tires at Discount Tire — CLICK for info – Only valid on the 3rd and 4th
$30 off 4 Tires with their credit card – CLICK for INFO
So, thats $130 off a set of any 4 Tires.
Be sure to comparison shop, then call Discount Tire with your best price. Price must be out the door with no add-ons or gimmicks.
They should match the price. Also they provide FREE balance and rotation.
