For the last 2+ years I've been buying my reef crystals through amazon. It's always been priced $45-50 for the 200 gallon mix and delivered for free. I haven't been that pleased with the salt and was looking into alternatives but have had a hard time finding other brands in bulk online for a reasonable price. I live in Buckhead, so going to the local stores is a bit of a trip plus I have lug a ton of salt because of my system size. Ideally based on some research I've done, I'd either like salinty or Red Sea pro. I go through about a box of reef crystals a month. Any secrets out there I'm missing?
