Staples.com InkDrop:
"When your ink cartridge runs out, drop a new one in your printer and mail us the empty one using a prepaid InkDrop envelope or mailing label. We'll send you a replacement before you run out."My friend Marc just told me about this new program from Staples.
I was out of HP 56 Black Ink for a week before picking up a three pack at BJ's today.
InkDrop would have solved my running out of ink problem. I like it.
