Okay, I have some cigars which I want to keep for sentimental reasons, but I don't want to pay $150 for a humidor (the cigars are not that expensive). What are some inexpensive ways to keep these things over a long term (like 15 years).

In my family we smoke a certain brand of cigars at births and weddings. These cigars are from the births of my daughters, and I would lover to keep them smokable until they eventually get married. that way I am smoking the same cigars at their wedding as i smoked at their births. I do not smoke cigars regularly, and don't want to incur the expense of a humidor. Any input is greatly appreciated.
