Absolutely! Of course, the routes and shops and such might be more tricky but with the right apps and companies, stopping for free WiFi and such you could easily grab up a few shops each day. Suppose you picked up two $15-$20 shops a day that wouldn't take away from what you're doing... if you did 25 days worth out of a month, you could make an extra grand. The key would be knowing who has shops at what locations and where to eye ball for them. I would also suggest getting apps if you have a smart phone.
