Deals on Weber gear are fairly rare. I believe the line is under a MAP agreement. MAP = minimum advertised priced. It’s an agreement between manufacturer’s and resellers to maintain a minimum price.
Most of the Weber deals I see are in store clearance sorts of things and one-offs.
As of this posting, Lowe’s has the 22 inch kettle charcoal grill for $109. Note that you have to add the grill to your cart to see the price. When you add it to your cart… it’s a private offer and not an advertised sale.
Price, promotions and availability can change quickly. Check the product page for current price, description and availability.
