It's impossible to buy the kind of publicity Healthy Choice received from this. The story has even been picked up by a paper in London.
To top it off they have someone who's not a paid spokesperson saying on national TV thant he likes the product - that's priceless.
Yes, they'll be smarter next time. The Kellogg's cereal promotion, which must have some connection to Healthy Choice as it includes their cereals, is limited to specially marked packages, giving the company much more control. But I suspect this would have happened even if Pudding Guy wasn't involved as there were enough other people in on the pudding deal to make them realize they'd made a mistake.
