Dang, I never thought I’d use up the last of the 300 cartridges I bought in 12/19 for $28 shippped, but here I am.
(I did quickly overcome the shyness of marching into the store, monthly, with a zip-loc bag jammed with 20 dirty beat-up cartridges, asking to “recycle” them.) Lately the cashiers don’t even bother to count, knowing the magic number is 20.
Now on eBay, it seems that cartridge lots like that have doubled or more.
I do see some semi-reasonable (per-cartridge) deals on huge lots, i.e. 450, 900, etc, but I suspect any investment that way would result in Staples suddenly changing the ink rewards game rules.
Any leads out there on a low-cost way to keep playing this game?
