Here’s one of the best deals I’ve found on printer ink cartridges and toner! Save $10 off a $10+ purchase with email sign-up at CompandSave.com when you enter the code NEWS10OFF at checkout. I regularly buy replacement cartridges from this site and can vouch for them personally! They work just fine with my printer and I’ve never had any issues with quality or compatibility.
After the coupon I got this HP 61XL Black Ink Cartridge for $5.49. Shipping is a flat rate of $3.99, so my total was $9.48. This HP Cartridge sells for $29.48 at Walmart, for comparison.
