Publix Supermarkets is offering a free reusable bag plus $1 off if you buy a two-pack of GE Energy Smart 10, 13, 20 or 26-watt compact fluorescent light bulbs. Unlike most Publix deals, this one requires a coupon. This Earth Day special is good through Wednesday, April 22.

While you’re at Publix, check out this week’s buy one, get one free deals, good through Wednesday, April 22. I want the M&Ms, but I’ll probably buy the yogurt instead.

Our friend Leah, who tipped us off to this Publix deal, has some other Earth Day freebies on her Suddenly Frugal blog.
