Walgreens is offering a free 8x10 collage print when you order online and use the code VDAY at checkout.
Shipping should be free when you choose in-store pickup.
My local store did not offer in-store pick up on collage prints when I signed up for a similar offer in the past, but luckily we travel a lot, so I just arranged to pick it up at a different location.
Here's a link to Walgreens' online photo department.
This offer is good 2/11 and 2/12 only.
UPDATE: Some people are reporting it is 2/12 only.
Thanks, Freebie Blogger!
