I did about 85 + of these shops in 3 days which I found to be fun and lucrative because they were so bunched together I did not even have to drive very far. I had one small issue with the email. You need to keep being persistent on getting a working email because otherwise you are missing out on a great opportunity. I have NOT been paid yet so I cant say for certain that the numbers will match to what I believe I actually did. The worst part is that there was no way to see what you did in the past, so do yourself a favor and record keep better than I did. In fact, I would turn on your google location settings to map everywhere you drive and where you stop for this because that would be the only way at this point I can prove what I did if something goes wrong.
