Today and tomorrow only, Shutterfly is giving away a free custom pet tags since it's Pet Appreciation Week (it is?). Simply use code LOVEMYPET at checkout and you'll get this $6.99 item at no cost (aside from shipping, which came out to a few dollars). Now comes the hard part of actually finding a photo of my dog where she doesn't look 100% derpy.
They've also got a Father's Day sale of 50% off cards, select photo books and calendars that ends today. Code BEST4DADS will help you out there.
