I bought the $40 deal - However, this is what the Groupon says - $40 Groupon: Each voucher valid for $20 worth of food and drink John's Pizza & Subs The amount paid for this voucher ($10.00) with John's Pizza & Subs NEVER EXPIRES. The promotional value expires December 17, 2013.

Correct: the amount paid for the voucher ($10) never expires -- the Groupon will always be worth and accepted what you paid for it. However, the current value of the Groupon ($20) does expire 90 days after purchase.
