Airline credit vouchers experts

[Luv2Roam]

DH and I are booked with Midwest Express (non-stop). I just checked. The flight is now selling for $57 less (total, not pp).
At booking, I spoke with a ME customer rep. I was told that if the price per ticket lowered less than $75, I would get credit vouchers for future flights. If the cost reduction was less more than $75 pp, I would be refunded the difference, minus a $75 fee.
We don't fly until January 5.
Do I wait until the last minute and see about credit vouchers? Or should I just ask for them now? Like the stock market -- isn't it?

unless they changed that its wrong. I used to work for them here in pittsburgh and we gave the credit vouchers for any amount. call back and speak to another agent. you're not changing the tkt. so why the change fee? it doesn't make any sense.
