I bought 2 gallon jugs from Amazon a couple of years ago, can't remember the price but it was much cheaper than buying dozens of the little bottle & still have some left. I just looked at Amazon, no bargain prices but it was there, all in the $20 plus range. Then I looked at Walmart.com, they have a gallon for $13.95, don't know what shipping would be but if you have a Walmart near you you can have it shipped to store at no shipping charge to you.
