Lowes had the Weber Spirit S-210 Stainless Steel 2-Burner Liquid Propane Gas Grill on sale for $249 plus in store. I've been watching this grill for a while and I've never seen it on sale at all, much less $200 off list price. There were two signs on the display. One stated it was on sale for $299 and another sign said the cashier could take another $50 off. See attached.
The E-210 and E-310 are also on sale.
