It doesn't really pay. I'm part of one (for Canada) that is legit and the pay is next to nothing. Most of it is like $10 per shop, and you have to buy something (which is included in your $10 fee) and you have to get transportation... All in all, it isn't worth your time to check the site frequently or read the weekly emails in order to snag a shop that's on your route or within 20 minutes of home once a month and make $10 minus the purchase you have to make. Even the restaurant ones rarely cover a whole meal for 2 people.

In vain I have struggled. It will not do. My feelings will not be repressed.
You must allow me to tell you how ardently I admire and love you.
