Question: is there gonna be an immunity challenge?
Or was buying it the challenge?

Buying it was the challenge.

Final Item:

1. Hidden Item-Anthony ($500)
2. Immunity from the vote tonight-Jacob ($500)
3. Hidden Item-Rico ($500)
4. An extra vote for tonight's tribal council. Corinne ($500) (Sorry Joey, but with a sub, you gotta be even more with the rules)
5. A vote spy from PREVIOUS votes. -Joey (Since he was the only one not to purchase anything, and since the other items are taken, he automatically receives this item)
6. Hidden Item-Eric ($500)
