Dwight and Church do not want to deal with Seller Support or respond to the buyer messages. They want to maximize efficiency at the manufacturing level. Amazon does not want overstock to capture every sale. The smallness of a reseller vs the bigness of a multinational allows for quick decisions to redeploy inventory to the demand. A majority of resellers on Amazon are operating for less than the time value of their money and effort. Amazon, Dwight and Church and the Consumer all benefit from this. The successful sellers find a way to be efficient and turn their efforts into a business.
