After purchasing my tires at big O tires, I had to wait till the next day to get them installed since they weren't in stock, I got a phone call saying that the sales person did something he shouldn't and the price is too low so we are going to have to charge you more for the tires, after I already paid for them.
So I took my receipt to discount tires and they were like we can match that price no problem. They slapped four tires on my truck and off I went to get a refund at Big O.
Plus at discount I didn't have to fight off them from trying to align my truck, or put new breaks on, or change my shocks, etc. They are just good honest people and everyone should just go to discount tire.
