I've done business with these people for years. I was always cautious, knowing that they'll try to nickle and dime you for everything. I would get a total price with all the hidden details before having them do anything and they never charged me more. I thought I was safe, but they got me, too. I bought 4 tires on sale with 90 days the same as cash-at least that's what the salesman told me. The condition was that you had to use the Firestone credit card and pay within 90 days. I paid in full with 2 payments within 58 days of receiving my bill. Now they are trying to charge me interest and $50 late fees. Not only is this business dishonest, but their finance division as well. I had them cancel my credit card and told them I would take my business elsewhere and recommend you do the same!
