Thanks for everyone who has offered to help and given great suggestions.
I have the eggs and prizes covered, some friends of mine are helping me out with this project. We decided to do one big egg of candy for each Soldier because there are over 200 in the unit, and then 20 of the eggs will also have notes in them that they won a prize. We will send 20 prizes that they can choose from. We decided on $10 iTune cards, the micro Leatherman multitools, DVDs of new movies, Gillette hygiene gift sets (shower gel, razor, blades, shaving cream), ans for the ladies a couple sets of Bath & Body Works stuff (shower gel, body spray, lotion) and some current magazines.
Phillis did this last year for one of her contacts in A-stan and it was a huge hit. Of course, her contact who handed out the Easter eggs took a lot of ribbing for being the 'Easter Bunny' but he said it was worth it to see everyone's smiles and the excitement of the person who won the prize!
