Bill D & co., it's those stupid 'bubble packs' they sell things in that are where so many of the bad deals crop up.   You want to go to the hardware or paint store and buy a box of 100 blades. You get stuck with a lifetime supply, but it's for the price of a couple of little ripoff packs.

Similar to buying a few screws & bolts in a bubble pack instead of having the hardware guy count some out of a bin for you.

Baker's yeast is like $3 a pound in bulk and $22 and up if you buy it in those little envelopes.

Spices sold in little bottles by the major companies. Ridiculous compared to bulk.
