If you're on Facebook at all you've probably seen an ad or a post from Postfly Box, or, maybe you're living under a rock and haven't heard of them. For those of you who are out of the loop, let's give a brief rundown of what Postfly Box is. Postfly Box is a monthly subscription box that caters to the fly-fishermen of the world, a group that they endearingly refer to as tribesmen. If you're unfamiliar with the marketing structure of these monthly subscription services, here it is in a nutshell. A person signs up for the service that they want by a certain deadline, once that deadline passes your credit card is charged and subscriptions are sent out, all over the country and the world. For you National Lampoon's Christmas Vacation fans, think of the Jelly of the Month Club! There are subscription boxes that run the gamut of interests, from Star Wars to home crafts and everything in between.
