missbev, I am also retired and supplementing social security. Generally, no one shop will be lucrative. You will need to do several shops in a day to have a good day. Start off doing one shop a day, then work your way up to two a day and then three. Soon you'll be doing several shops a day. Depending on where you live, you may have to drive a good distance to keep this going. I started out taking whatever I could get, now I specialize in banks and service stations with a few odds and ends thrown into the mix. You will, of course, need to be signed up with a bunch of companies to find enough work.
