Vantaggi
You make your own hours and days. Most jobs start on Sunday but a few small jobs start on Saturday. Every job I was assigned had three days to complete it so you did not have to work the weekend unless you chose to do so. I scanned very fast so being paid per item scanned worked in my favor. For example say you have to do an entire store by yourself. The number of items needing to be scanned does not change so the pay is the same no matter who completes the store, but I can do the store in 18 hours or less if I didn't get distracted. That's two nine hour days for me, but if you scan at the company average speed that could be four days of work for the same pay I made in two days. I never complained about having an entire store to myself. The pay is different around the nation of course but at my rate a whole store was $500 in two days of work, you do the math. I had never used a scanner before this job or had any 10 key experience. They pay you for mileage after the first 30 miles and any drive time over 30 minutes. I don't know about the rest of you but I've driven more then 15 miles one way for a job and spent well over an hour a day in the car to go back and forth to work with no compensation at all. When you agreed to the job you agreed to go at least 60 miles one way if needed. They try to avoid that but if you have to the compensation isn't horrible. If you drove say an hour away and 100 miles round trip you'd get about $35 just to drive. I know plenty of people commuting that far and they don't get any compensation.

Lapel is harder (gathering prices at a store that doesn't allow it) but the pay is 3X greater at the easier locations and 5.5X greater at the more difficult locations. And really the only thing that makes it harder is being nervous about it. Yes you can be asked to leave, but that only happened to me a few times over the years I worked there and once was my own fault for blazing in there with my scanner lol. Your cell phone with a recorder app can really be amazing. I wasn't personally interested in advancing because I liked my position but there was never any opportunity for me to do so presented in my time there either. New managers were always coming in but they were clearly new to the company because they would come into the field and learn the job by working with us.
