"Knowing who you're dealing with: get the seller's phone number and postal address"...
this is one of the golden rules for secure on-line shopping. Some on-line stores do not have office or warehouse.
What they have are just their web-site storefonts, but nothing else; no physical office/ address, no contact telephone, no fax, no staff, no stock.
