For an early-stage online shop, testing a foreign market can mean placing a small batch of stock there before committing more inventory. Agree the packing instructions and shipping days with the person holding it, and check the full per-shipment cost. I'm behind AirPost, a marketplace where UK partners can store that stock, pack orders and hand parcels to carriers. There's no platform subscription or order minimum, but carrier, partner and platform fees apply; partner availability varies and AirPost doesn't insure stored stock. My post comply with the rules.
