You want sample sizes of food?  TheFerretStore.com has little 4(?) oz.
sample bags of their food.
 
Don't want to spend $20 for ferret food?  Well, first of all, for $20 you
get a LOT of The Ferret Store's food.  And, in the long run, think of the
money you'll save by having healthy ferrets!  Vets cost more than good
food.
 
Good luck,
Chana
Whose ferrets eat better than *she* does!
