Different markets attract different customers. The markets decide success or failure. These stores seem to be popping-up everywhere.
Personally, Amazon is our household favorite. With delivery to the house, from either the Amazon Nashua warehouse, other warehouses, or third party shippers, it's great convenience.
UPS and USPS partnering to deliver, is a win-win for all.
Regarding this store becoming the MoBo gym ... it could be called the Ship-to-Shore or Ship-to-MoBo!
