We recently purchased a Weber Summit S470 natural gas grill (at a very good price, plus we took advantage of the discounted sales tax). After having it delivered and setup on our deck (which is on the second level in the rear of our home), we realized that we had more than enough room for the larger S670. The folks at Derby (our salesman Clarence as well as the owner, Mark) were willing to allow us to upgrade and they redelivered the larger, HEAVIER S670 (yes, up those 12+ stairs again) and took back the S470 (yes, DOWN the stairs).Our experience at Derby was terrific and were very happy and enjoying our new grill.
