Like everything else, grill covers vary in their pricing depending on the company, product details, size, shape, etc. However, generally grill covers are not too overpriced. They are, on an average, around twenty to seventy dollars, depending on which product you select. If you are hesitant to pay anywhere in this price range, consider if you did not have a grill cover and just left your grill outside in the open. The damage that would possibly and probably be done to the grill would cause you to have to buy an entirely new one, which would be more expensive in the long run.
