Seeking resources and examples for starting a subscription business for physical goods

My business idea is a subscription service for monthly samples of a very specific food item. Simply put, users would subscribe for a varying monthly fee based on their preferences (quantity, varieties, etc.). They would then receive a monthly sample box based on those preferences. I would hope to work out some sort of deal (in the form of drop shipment, overstock/wholesale purchasing, etc.) with small-medium manufacturers that would allow me to earn on the margins, as well as a premium for the service of delivering products that a user would not find at their local grocery stores.

My initial concerns are for the logistical overhead of managing varied deliveries of products from varied manufacturers. That is to say, I can see needing a physical location to have items received, organized, boxed, and shipped from. As I am a freelance web developer with indefinite travel plans on the horizon, I would also require an employee/partner that I trusted to handle this end of the work.

Years ago, I actually worked a summer internship doing procurement, shipping, and daily accounting for a small manufacturer. So the requirements and workflow of that setup seem quite straightforward to me.

I know there are examples of similarly structured subscription businesses out there. I just can't think of many. Blue Apron, Trunk Club, and Dollar Shave Club are some "big names" I can think of. Can anyone here give some examples of smaller operations with a physical/edible goods subscription structure? Are there any covered here on IH?

Any other resources in the form of interviews, forum threads, or blog posts are greatly appreciated too!
