If you have a Vons card, go here right now to add an e-coupon for a free box of clementines to your card. Because it will be pre-loaded to your card, it should come off automatically at checkout.
The coupon is limited to the first 25,000 people who put it on their card, and the coupon is only available to use TODAY. Also, a minimum purchase of $25 is required.
Thanks to Crystal, The Thrifty Mama (and one ofy very favorite thrifty bloggers) for pointing out this deal!
