so I've been drop shipping some parts. i make some kits up and list them on eBay. so for example it requires 4 parts each having their own sku number. now i can have multiple mpu but not sku on ebay. this is the way ive been getting around it manually. but this way ive not been able to automatically update their stock on my listings (i can get stock sheets as a csv file from them) and keep updating stock levels from their csv file. hard to describe the issue im having but i need to have mpu work with sku.
