These are only good for 14 consecutive days. If I remember correctly they are stamped with the first day of use. You could attempt to sell them I guess but to whom that would be the question. Second option you could find a nice family down there and give them to them as a kindness. Thirdly, you could do nothing and let them expire. That's about all the options you have available to you. I hope this is what you were asking.
