Product ID and SKU

The SKU will be generated by Amazon IF you do not choose it yourself.
Many sellers make their own SKu’s to enable them to better keep track of their stock, and can, for example, utilise the SKU to help locate where in their storage facility [whether that be spare bedroom or warehouse] the item is located by allocating a coded SKU.
