I was surprised when I see many inks were marked clearance with very low price. For example Epson T008 color from $19 is marked $7, and T007 black from $22 is now $8. Picked a few for my Epson 785-EPX.
Many other Epson and Canon inks on clearance but can't remember all of them. Clearance price between $7 and $9. Probably for older models.
