The price on Amazon fluctuates wildly as you could see from camelcamelcamel's chart:
DrTim's Aquatics Ammonium chloride - 2 oz bottle (B006MP4QG6) | Amazon price tracker / tracking, Amazon price history charts, Amazon price watches, Amazon price drop alerts | camelcamelcamel.com
It is down to $2 a bottle now for ADD-on to a Prime order, of course you need to be a Prime member.
When it goes this cheap I like to buy a couple for new startups.
