If you are still holding onto unused Lummi Island ferry punchcards that expired on June 1st, you have a limited time to exchange them for credit toward new cards.  With the summer car and driver rate up to $10 per trip, purchase of a new 10 trip punch card at $72 will save you $2.80 per trip, and purchase of a 25 trip punch card at $160 will save $3.60 per trip.  It’s worth stopping at the 2nd floor of 322 N Commercial St (across from the library lawn). . . or call 360-676-6876 and they will tell you how to exchange your old cards by mail.  The deadline for exchange is August 29th. Â
