I somehow missed the announcement that expirations were beginning again. Does anyone have a good strategy on an easy way to extend expiration if immediate future plans don't include any Frontier flights?

I found these threads:
Miles expiration?
Extending account miles without flying? Accrual options.

It seems, short of flying, the options are:
-credit a rental car (Dollar, Thrifty, Hertz, Budget, Avis, National, Alamo)
-hotel stay (Marriott, Radisson, Wyndham)
-transfer hotel points (Radisson - 10:1, 2K Radisson minimum; Marriott 3:1, 3K Marriott minimum; Wyndham 5:1, 6K Wyndham minimum)
-shop with Teleflora (10 miles/$)
-join Vinesse Wine club (6 wines, $42, 1500 miles)
-buy points ($25 for 1K)

Did I miss any easier option? Is there a way to gift points to another member (even if there is a small fee?)
