When I bought my stove, it was 'brand new, in a crate, ready to go, sitting in the stock room'. I bought it sight unseen over the phone with credit card. I had some issues getting it, getting help to get it, plus life got in the way, and I called asking if they had the space to store it safely for a couple of months. Sure they said, no problem. Well when I went to pickup my stove, turns out the one they had 'set aside' was sitting inside the showroom off the crate but "good news, we just got an order in, you are getting a new one on a crate for last years pricing".
If you are able to check and make sure all the parts are there (handles, ash pan, bolts, spare gasket material if it has it, stove paint if included) then do so. Make sure everything seals well, there is no damage (take a high powered flashlight with you). If it all checks out, and there are no bad reviews for that specific make/model/year, then heck ya take the discount and bring it home. Assuming they have the original pallet to safely haul it back. Mine had a pallet with steel supports to keep the weight off the legs for example for shipping. It was also nicely wrapped. When transporting a stove in an open air container (back of truck, trailer etc) make sure to face the stove glass facing the back. A stone kicked up on my way home with my stove and smashed into the back of the stoves crate and put a nice little dent into it. Another inch away it would have hit the stove, and if I had the glass facing forward, a busted glass for sure.
