Mobile coupons are a great idea: they save paper and mean that retailers might be able to text deals and future coupons to their customers once they nab the coupon and opt in. William was pretty annoyed at Target’s mobile coupon this week in practice, though. He waited to text Target for their $10 off $40 deal until he found something that cost more than $40 that he wanted. Why waste a text message and waste his time, right?

So he sent away for the coupon once he was in the store. That’s when he learned that he really should have planned ahead.

TARGET: Thank you for your interest in Target’s Spring Cleaning campaign. Your $10 off coupon will be available within 24 hours. Msg&data rates may apply
