Hi. Or is it just my local supermarkets? I've tried to buy either Finish "turbo dry" or Fairy "active drying system" and can't find them anywhere. Our dishwasher is not suited to those 5-in-1 type tablets so we need a separate rinse aid and, as we are tupperware family extraordinaire, the ones with extra drying action are fab - in fact, nothing else will get the plastic stuff completely dry. I've found one place to buy online but they charge postage by weight so it'll cost a lot to bulk buy. TIA.
