Seems that if you book and cancel they will refund them and they'll be good for another year.
I've thought of this but all I could think of is that they might charge your credit card for the value of the Orbucks if they were used, but I doubt they would do it, my guess being it would work.
Thanks. Will try that. (I guess that was the first thing I should have tried)
I didn't look into this, but I think there are different kinds of bucks. The website says they'll expire in 15 days and I only earned them within the last few months.
Doubt they would charge my card (even if they would, it's disputable. Not anyone I owe money to can charge my card, it has to be a transaction I made). Anyway, I think all the cards ever associated with my account are long cancelled.
