My time is worth more to me. I have a job... And I highly doubt that standing in line at 4am for hours on end in the cold, and then listing online and shipping stuff or driving to meet people, is gonna pay me anywhere near what I am already making working from home...
If someone has lots of free time and doesn't have a real job, then maybe the $20-$30 an hour profit they make is worthwhile. For some of us, that time spent isn't worth it for us at that price...
So you like me are too lazy for it. The ROI is too low.
