After speaking with 2 MS CMs, and 2 Supervisors, here is the "official" answer:
1. If you purchase the vouchers, they must be redeemed by January 31, 2015
2. If you do not redeem the vouchers by January 31st, they will expire, and can not be redeemed.
3. Purchase of vouchers is non-refundable.
4. If voucher is not redeemed by January 31, 2015, you can get a credit for the purchase amount, and apply this towards new tickets/media of your choice. Tickets/media will be sold at whatever the cost is at the time the credit is used.
The reason I talked to so many people was #4. The first 3 responses I received was that if you didn't activate your voucher by 1/31/15, "too bad, so sad". No refund. No tickets. Nada. I pointed out that this probably wasn't correct because it meant that the purchaser would be getting nothing in consideration for the initial funds rendered. First 3 people didn't think it mattered. Fourth person immediately knew what I was talking about and gave me the answer above, which I find reasonable. She said it's what they did with the last offer if people couldn't redeem their vouchers for some reason by 12/31/14. She also put a note of the policy in our MS file. Hopefully, we won't need it, and if we do, they will be able to find it!
