ComboInk is having a 15% off sale through 5/15 when you use promo code MOMMY at check out.  I’ve updated the sidebar ad to reflect their May promotions.  Knock on wood, I’ve had no problems/issues with the cartridges I’ve bought from them.  And honestly, I was prepared for a slight bit of inconvenience or some trouble given the extremely low prices they charge, but NOTHING!  So yes, I can completely recommend them; I’m using their clones of HP laser and color cartridges.  I see they have a combo deal..says you can save up to 80%.
