I have had TF shipped to me, via ups 3 day, twice now.  Each time it came in
a box with no reference to ferrets.  It does contain the retailer's name
"NEEPS" in the return address, but that probably means little to anyone not
up on ferret suppliers.  This supplier can be found at
http://www.TheFerretStore.com/items/tffoodmain.html
They show a price list and a toll-free tel #.
 
Hope this helps,
Glenn
