I think I'd take the 1 in a bunch chance that someone goes through my garbage and just throw it away rather than driving 12 hours to the coast and renting a boat. That's practically at radioactive waste levels of inconvenience.Put the destroyed card in a taped sock with some rocks and throw it in the deep sea somewhere the public doesn't regularly go to. Spray paint the tape so it looks similar to seabed sediments and not even the microorganisms will find it.
Just mail the card back to them or buy some cheap sheet metal cutters at Home Depot or off of Amazon.
