This price has everything to do with what consumers will pay for convenience and almost nothing to do with manufacturing costs, which are a tiny fraction of that. (Shipping and delivery are probably more, both for energy and labor.) Sellers do not determine the market price for anything. Buyers do by what they will pay. Sellers can specify a price, but any transaction actually happening is only determined by the buyer. (Setting the price can be intended to apply psychological manipulation to the buyer, which often works.) If you are complaining about the prices of anything, your complaint is not with the seller, it is with other buyers who have proven they are willing to pay it.
