I think I'm on the DTD mailing list and I haven't received anything yet.
The last time I bought tires was two years ago on Black Friday when DTD had $50 off four tires and it would stack with any rebates. So, I saved $100 total on my Hankook H727s.
Costco has $70 off all the time. DTD often has excellent deals. They've had quite a few this Fall. I bought my new Coopers at $150 off instant and mail-in rebates.
