Get 15% off your 123InkJets order and free shipping via code FLAG10 through 5/29. Better yet, buy three or more to get extra savings on most ink cartridges. For example, the pictured Remanufactured High Yield Black Ink for HP 564XL (which works with the HP Photosmart 7510 and more) drops from $9.99 to $8.99. With free shipping, that's the best deal by more than $3 from a trusted seller. Plus, get three or more and they fall to $8.10 each with the coupon. Note that this coupon does not work on hardware and OEM products.
