I don't know what level you consider "monster" for shipping charges, but AquariumFish.net has the dwarf puffers for $5.50 each, plus $24.95 for shipping, no matter how many fish you get. If you can't find them elsewhere, you might give them a try. I've never dealt with this company, so I can't vouch for it, but they do have them for what seems to be a reasonable price.
