Grizzly prices it stuff very competatively, and does not discount price, they usually have sale fliers twice a year, and the Tent sale once a year (different times for each location). The prices at the tent sale are not a great bargin in dollars, if the machine is anywhere near operational condition. (there is a very good reason that the price is reduced, like cracked casting, or missing many parts). If you are not there early, there will not be much left to chose from. The items may be RTV, shipping damage, or discontinued.
The Web site section for discontinued tools does have some realy good values, if you are the lucky one.
Shipping damage has been a issue with some Grizzly tools, but that is not "really" Grizzly's fault. But I would check over everything, before "signing off" to a deliveryman. Grizzly has in the past made outstanding efforts to correct problems. I have only purchased "large" stuff on site and used my own truck to transport. I use shipping only for the "small/light" stuff between my truck runs.
The big advantage of Grizzly is more the service after the sale, then a stricly "lowest price" approach to sales.
Today I will gladly share my experience and advice, for there no sweeter words than "I told you so."
