I do get a bit of discount from them (5%). Mostly it's just really convenient since they save me a lot of time by doing the packaging on site. Maybe if I reached really big volume then it would start making sense. The price of product is only 23% of the cost even now. Shipping is the biggest one at 33%.
Would it reduce your shipping costs if you shipped all candy to your US subscribers to one person in the US, who would then mail out the individual packages? Just a thought.
At the scale I am in, I doubt anyone wants to talk with me since I'm only buying $1000 worth of their product (I cycle through different candy so don't buy that much from single manufacturers) as it is. Also not all of my subscribers are in the US, I have many in Canada, Germany and all over the place.
