Walgreens offers its 4" x 6" or 4" x 4" Photo PrintBook from $6.99. Coupon code "FREEBOOK" makes it free. Opt for in-store pickup to dodge the $6.99 shipping fee. That's $2 under our December mention, a savings of $7, and the lowest price we've seen.
With these companies, it might be easier than you think to negotiate your monthly bill down.
