I have an Epson Stylus Photo 820. I was going to try some Epson-compatible cartridges from MaVieRose, but she doesn't currently carry them for my printer.
I've heard good things about Carrot - http://carrotink.com for a couple of years now, and they have great prices, so I thought I'd take the plunge.
I got a "carrot bundle" of 2 black and 2 color, for $52.80. Standard shipping would have been $4.95 (they charge actual UPS or USPS rate based on the items you order). I opted instead for the $7.95 overnight shipping.
At Staples they cost $21.49/ea for color and $24.99/ea for black, and that's the best price locally.
I placed the order late yesterday afternoon and the cartridges came today via FedEx. :) Their customer service, both via e-mail and phone, has been very quick to respond, friendly and helpful. They're a small family-run business and I like supporting such when I can.
I'll let you know how they work!
