While the idea of shipping shoes to get shined seems ridiculous on the cover, I quickly forget that many of the owners of numerous high end shoes are CEOs, other executives, etc...
Many of which are worth way more than the populous and most definitely most of SF. If they want their shoes polished with the best possible quality and service why not ship to a Pro with no regard for cost. But then I'm sure many have in house butlers that can duly serve as shoe shiners as needed.
One day I'll be shipping my shoes for shining!
Let me introduce you the concept of a domestic staff. So tell me again why are people having a domestic staff or a personal valet mail their shoes for a shine?
