A couple of years ago I ended up getting my 4" Superlift lift and Rancho shocks and extended brake lines from them. I ordered the stuff over the phone and do not recall them being rude. Everything I ordered was shipped with no problems. At the time, they had the best prices on the lift and shocks.

As I look at prices of tires now, I don't seem to be able to beat the prices at Sam's.
Find the tire you want on their website; special order however many you want; tell it what store you are going to pick them up at; get contacted by Sam's when they arrive; go to Sam's to pick them up and then pay for them. You do not have to pay for them in advance.

I bought a set of seats for my old heep, price and customer service were satisfactory.
