Planning a pink and gold candy bar for my daughter’s sweet 16 in late June. Can I pick up bulk candy in the store or do I need to order online and how early could I buy the candy without freshness being an issue?

You may also consider ordering some gold and pink food color spray so that you don't have to find items that are originally gold and pink.

Call ahead definitely to ensure they have the weight you are seeking however they should have it available on site

Call them shouldnt be a problem

I'm not sure.... they do seem to have the capacity for that. I would call ahead
