I own and operate a single screen movie theatre in Vancouver British
Columbia.  I am interested in finding the best and cheapest source for
the following products.  I can purchase large quantities of these
products and don't mind stocking large quantities in order to get
large discounts. I also don't mind buying from the USA or even China
to get better prices.  I am looking for a major source not
local/wholesale distributors.  I am also looking for wholesale pricing
on these products if possible.

1.  Lined popcorn bags (small, medium, large)
2.  Popcorn Tubs (small, medium, large)
3.  Popcorn Flavoring (cheese flavour, salt and pepper etc)
4.  Wholesale popping kernels
5.  Coconut oil for popping
6.  Smoothie/Slushie mixes
7.  Nacho chips and cheese for theatres
8.  Kids combo trays
8.  other staple items available in the concession bar

Are you able to speak Chinese?  Can you provide samples?  I run a
small F&B (retail) in Shanghai and have access to most of the items
that you're looking for.  If you can speak Chinese, I can pass the
contact information on to you, if not, I can assist you in the
transaction (I have a colleague with a rest. in the US that orders
various items and I help them through).
