I have been buying my ink for my Epson printers from an eBay seller for years!
I don't think that the cartridges are refills or third party.
(If they are, they have always worked perfectly)
What would cost me $80.00 in the store cost me less than $10.00 from the seller!
It is very important to deal with a seller who has
Monstrous Positive feedback ratings and will ship for free or for very little!
As I said, I have been doing it this way for years and I've never had a problem!
My last purchase (below) would have cost me an arm and leg at a retail store.
(That price you see included free shipping)
