FREE color or black ink printer cartridge refill at participating Walgreen's, Wed, Sept 12th only.
My local store did not have an icon next to it signifying that they were participating, but I called them and they are, so don't go by that.
* Offer excludes Canon and Epson cartridges.
See the complete list of refillable printer cartridges. (look for the link on the bottom of the linked page)
