What's in our food?; The real deal with Value Village

They require warning labels in Europe, so why does Health Canada allow certain additives in our food? A Marketplace investigation finds food manufacturers are producing two different versions of the same snacks one with certain artificial additives for Canadians and the other without for European consumers. A health advocate says that needs to change.

Plus, we're teaming up with CBC's Street Cents to reveal the secrets behind Value Village pricing. Hosts Charlsie Agro and Mercedes Gaztambide go on a shopping spot check, testing whether you're really getting a good deal, and they find examples of markups on many household products - some still have the original price tag! We meet with an insider who shares why things are priced the way they are, and the lengths the company goes to make a profit.
