I looked into the Mazda buy 3 get 1 free and found that for the tires where the deal was offered the final price was very competitive - plus they claim they will price match. The Mazda price per tire looks high initially, but it includes mount, balance, disposal and 24 months of road hazard. But not all tires are included. IMO the Mazda deal is a good one and my local Mazda dealer is excellent, but I already have a preferred tire shop. I'm pretty loyal to Discount Tire. I like that they sell only tires and wheels - no alignments or repair services. Their selection is good, customer service is excellent and pricing is always competitive so I don't feel I have to shop around for price. Where I live there are Discount Tire shops convenient to my house and work - so they are a first choice.
