I found the refills for the ink cartridges on ebay. One is for Canon (free shipping) and one is for Epson (pay for shipping). What is the difference? They are both 4 colors and they aren't cartridges.

I want o order them, but if they are the same, why should I pay for shipping. Anybody know? TIA

anyone know about this?

I don't think it matters, since you're only ordering the liquid colorant, not the cartridges.
