If you are buying just the chemicals, make sure you get a metal container seals as it will eat plastic and will evaporate and not to forget the smell is very over powering.

I usually buy the 5 gallon buckets from NAPA since most of the other stores don't carry it in a container that large. I paid $112 for it with tax but no basket. The 3 gallon with basket is about $57 plus tax.
