I have the Capital One Shopping app installed on my browser. It tracks purchases and any time I shop and when I purchase using the app's coupons it finds. Over the last few weeks as I researched tires at Tire Rack for myself and someone else on the forum that was looking for all season tires, each day after I'd research tires I'd get an email from Capital One Shopping showing a tire I'd looked at and offering a discount if I clicked the link in the email and completed the purchase within 24 hours. At first the discount offered was 3.5%, then $29.38, then last week it was offering 30% back. The rebates were available at Tire Rack (or any Firestone/Bridgestone dealer) last week, so I pulled the trigger. The total rewards was $220.78 from Capital One. The tires themselvers were $595 after rebate. After the Capital One rewards, they were $374.22 for the set. Retail from the BigO Tires across the street from my shop is $808 for the set.
