Hi Pat;

Probably 75% of the forum users have less than 12,000 gallons of water in their pool; for them, 1# of stabilizer is 10ppm. So, wholesale quantities usually don't make sense.

Also, if you buy from the grocery store . . . or Sams Club . . . there may not be any advantage:
+ baking soda => from Sams: $0.30 for 12#; wholesale: $0.20 for 100#
+ cal chloride => RARELY needed, but available economically as ice melting salt.
+ bleach => wholesale quantities are perishable
+ dichlor => $2/lb at Sams for 50#; this is below wholesale in many areas
+ borax => ~$0.65/lb at Walmart; possibly 0.30/lb wholesale for 100#, but hard to find

The three chemicals that are often much cheaper at wholesale -- cyanuric acid, polyquat & HEDP -- are not usable on home pools in wholesale quantities.

So, while purchasing wholesale may work for a few, in select localities, it's not generally a practical option.

Thanks for posting.
