I just reviewed the July 10 Staples ad. They had HP920XL ink ON SALE for $31.99!
Then....I checked SimplyInk.com. The same ink cartridge is $9.89 with their additional 10% off!
I LOVE Simply Ink! The shipping is very fast and they have the cheapest prices for ink around!
Friends are constantly telling me that they spend $40 to $50 on ink. Once you sign up, you get reminders to re-order ink and discount codes from SimplyInk!
