Here’s an interesting cross-promo. Reader Ally spotted a pack of Duracells at her lokcal Hannaford that came with a FREE glue stick. It wasn’t something that the store had shrinkwrapped together, but the glue stick was actually in the package itself. What’s the marketing strategy here? Maybe because they’re both supplies you put in your desk drawer. Maybe the glue makes the electrons stick together better. Inquiring minds want to know.
