Yesterday, I picked up a three pack of HP printer cartridges (black number 56) at Costco for around $50 - great deal! Anyway, I just jammed my pair of orange handled scissors into the blister pack and used my super human strength and only a few French words as I pried one of the cartridges out.
And what to my wondering eyes did appear, but a postage paid envelope for me to send my empty ink cartridge back to HP to recycle. I was thrilled! I usually take my old one wrapped in paper towel to Officemax or O-depot and turn it in for my $3 credit. I didn't mind losing the credit for the incredible ease of popping the cute green envelope in the mailbox for Dale to pick up today.
Thanks HP! Enjoy!
