In at least some jurisdictions, not that purchases of alcohol would not count for the $10 or earn any points.

SQ redeemable miles have a hard expiration date, IIRC three years after they were earned/credited to the account.

Somewhat OT, but several years ago BestBuy had a frequent buyer program with points expiring at the end of the calendar year in which they were earned. I haven't purchased anything there since then, so I don't know whether there's still a program with the same rules.
