I'm also open if anyone know of good deals on salt locally or online with free shipping, "I don't really care what brand though I've only ever bought reef crystals"

This is a sack, no bucket, so I recommend immediately putting it into a sealable bucket otherwise it'll spoil - you can also buy it in a bucket but it's less cost effective. They also have IO and a bunch of other salts, but I think IO and RS salt cost the same. Depending on your target parameters RS blue bucket might fit you better.
I bought from them before. Free shipping even on salt, and it was decently fast considering it was free. Saves gas and time on your part.
Smallish business, far smaller than BRS for sure.
