I have found stores like Ritz and Wolf to have ridiculously high prices for the chemicals, paper, etc. that they have, which may be one of the reasons they can't move an inventory and decide to eliminate it instead. Until mail order starts to be dangerous on the products from irradiation, etc., that will remain the best option. I have ample supplies locally at good prices, but they still can't beat mail order on most items.(posted 8276 days ago)Beer is one of the few products with a shorter shelf life than developer. That's why it's important to consume it on a regular basis in order to insure proper product rotation.
