If you have a Borders or Waldenbooks nearby, you might want to check out there clearance section, maybe you'll be lucky and find some cheap book on tomatoes or gardening. I'm not sure if its acceptable, but you could maybe break up a bag of Tomatotone and put a tomatoes (or two or whatever) worth of fertilizer in a small paper lunch bag. Another thing might be to make a bag of spaghetti herbs/spices.
Personally as a grower I could always use more things to tie my plants up
