Well, I finally broke down and ordered a laser cartridge for me and a set of color and black cartridges for FirstBorn.  I got 12% off Ink and Toner – with promo code GREEN12 or CLOVER.  This brought the order down to $50.99, so free shipping.  Of course, the regular shipping is only $3.99, so not a make or break deal here and I refuse to be put in the position of hitting up Staples for printer ink emergencies.
