I know some of Home Depots sales have already been mentioned but I stopped in my local store to pick up a few things and saw they had the 26 on sale as previously mentioned. I also noticed they had a sear grate left and it was marked down to $18! That is cheaper than the regular replacement hinged grate. I think the same deal popped up in St. Louis....
I stopped at the customer service desk and was told the sale is regional and not all stores are marking down this item. In fact, one store a few miles away, was still regular price because it was in a different region.
If you haven't checked yet, it may be worth a shot. I plan to use the heavier grate in this set as a replacement for the standard one.
