$4 shipping any size order. $3-$10 Epson cartridges.
I have been planning on buying from these folks for my new cartridges but I still have a box of cartidges for my 740 and 850 from ValueAmerica half price valuebuck deals. I just bought the Epson 1200 on the $150 deal and plan on getting some carts from these folks.
I have had flawless service from aftermarket ink jet carts in color and black for my 740 and 850. I have used generic carts from ComputerGeeks.com called GraphicUtilites, and NCR carts that I bought from ValueAmerica. I have found the color indiscernable to OEM Epson cartridges, but I have no info on their color fastness.
Someone has posted on Anand or FatWallet that these folks have a good product, if anyone has personal experience with them please post.
Cheaper chinese carts are available for Epson chipped cartridge printers,
Epson Stylus Photo 870, etc. aftermarket carts for $18 and $19
Do not count on archival or water resistant prints though. I have seen no review and have no experience with these inks, but I would strongly suggest only using aftermartket carts for casual color printing. The new Epson inks have exceptional print quality and print longevity and you will not likely get comparable service from aftermarket products.
If you want some very good, and professional user information on ink jet use, this is the best site that I have found.
