Hi Kevin and welcome to the forum,
Sounds like you were on to a great deal there previously, no thanks to eBay making it as difficult as they possibly could on you. Consumables do tend to be hot and cold in the surplus market, so finding a regular constant supply of a particular product will most likely be a bit of a struggle. We've got a few excellent fully verified liquidators listed in our directory that are well worth checking out, but I have no clue as to their consumable stock currently.
One I would definitely speak to would be Via Trading. Even if they don't have anything, you may be able to convince them to keep an eye out for you.
There is also Link hidden: Login to view (NOT VERIFIED BY US), but certainly specialize in your genre if you want to take a look at them.
