Great question. I’ve had the heating unit sitting in my cart and I’m debating completing the order. I’m guessing everything is out of stock, which is the issue everywhere else. The heating unit is backordered until December, but folk have been able to find them here or there and I was hoping they had them in stock, but I can’t find info to confirm that.
My guess is, it’s probably legit. Also, whatever you ordered is probably not available. Guessing they’re just a storefront and don’t keep their own stock. They probably don’t update their site to reflect global inventory.
