Note: when you go to complete an offer, you have to turn off any popup blockers you have enabled. There are instructions that pop up from freeipods.com.
To use the eBay offer, you have to sign up with a NEW account and then bid on something. (Doesn't have to win the auction)
Also, I suggest using the Ancestry.com offer. It gives you instant completion of your offer. You must give them a credit card number to sign up, but you won't be charged if you cancel within about 12 days. Don't cancel immediately tho.
