I normally do full sized bars considering how many people we get on average. I normally buy them at Costco Business and it looks like they're still priced the same. Prices at regular Costco are similar to what I remember of last year too.

We probably make most of our chocolate here. In the area around where I work there are at least 4 Mondelez plants. I know Mars has a few plants in or around the GTA as well.
