Through May 16th, you can get a free 8×10 photo print (with no shipping!) from Snapfish when you use promo code SUPERMOM at checkout. These gifts are normally around $5 after shipping, so it's a nice little freebie for Mom!
If you forgot yesterday was Mother's Day and need to play it off somehow, just use my go-to excuse. I say I messed up and jumped a day backwards for Daylight Saving Time instead of an hour forward. You'd be surprised how often that works, in that people are usually too stunned to call you out on it!
