Most stuff I'm able to get whatever quantity I want pumped into our totes.     There are a few things that the retailers I deal with don't have the proper license ("repack" or something like that) to sell less than a full package and then we end up getting 2.5's.

I'm like you though, I'd rather have 60-80 gallons in a tote and keep refilling the same 1 or 2 jugs to dump in the sprayer than have 24 empty jugs to mess with/dispose of.
