I went to buy mascara to get ketchup which is .99c this week and found hp ink on clearance lucky for me the carthriges my printer uses were part of the clearance. This ink carthiges sell for 11 dollars at staples. i ended up saving a lot.
3 hp #02 on clearance for 3.79 each
paid 11.37 for 3 carthriges i would have paid this just for one.
