The RFID tags embedded in a glass bead that you inject into a dog cost 
about $3. The kind that are paper thin that you incorporate into a book 
lining cost about $0.25. The ones retailers buy in volume to tag random 
goods are likely in the $0.10 or less range.

Browse around here for examples:

(Though most list "call for pricing," some have prices listed.)

Or you could encourage privacy advocates to back off, so Walmart can go 
back to their original plan of tagging every product they sold (rather 
than just the pallets), and buy all your goods from Walmart so they come 
with free tags. :-)

(Walmart claimed they would fry the tags upon checkout, so technically 
that wouldn't work.)
