It's very easy to put up finger mullet for future use.  During the late summer, fall and early winter, when mullet are plentiful in the surf, I typically put a few dozen bags of mullet in the freezer.  When I return home from fishing at the beach, I simply dump out my left over mullet in the grass, rinse off the sand, and put them in pint and quart bags.  I put these in the freezer, and during the rest of the year, I just grab a bag or two and head to beach.  They thaw very quickly at the beach and are usally good for a couople more days if put them in the fridge between fishing trips.  Mind you I have an old fridge in the garage that is used mostly for bait (and a few beers) as it tends to smell a bit fishy.  {module Amazon Automatic}
