Former GS leader reporting for duty!
Make posters that have hand drawn huge cookies on em and make the girls take turns holding them up and walking around with another adult during booth sales, decorate your car windows with shoe polish saying "buy your GS cookies here"people will actually buy cookies from you at the gas station, grocery store, running errands, etc, make sure your scout is ALWAYS in her uniform when you are in sell mode to attract attention, ask smaller businesses in busy areas if you can set up a table out front to attract business for them, advertise in the paper that you are having a GS cookie Garage sale, unload some cookies AND clear out some clutter. Have a good carnival bark while at booth sales. "Our cookies will make you run fast and jump high if you eat enough!" (ppl loved that one lol) Gold's gym parking lot- nuff said, Bowling allies on league night- ask for permission then go lane to lane with your cutie, same goes with busy beauty salons with lots of hairdressers(you might get lucky and get a salon that will let you leave an order form. One of our Moms did this and even outsold my DD- once hehe) College and High School campuses- those kids miss their cookies! (we parked across the street in an empty lot just before school let out

)We even sold cookies at the post office LOL! I took my DD in office buildings and made a butt load of sales. Law offices, banks, utilities, etc. Call ahead and ask for permission, sign out lots of cases from your cookie parent, and load your car.
And that's the ones you can do with your scouts.....
I sold cookies to the grocery store employees and waited till midnight for them to get off work so they could buy them right out of my car, parked my decorated car at a gas station for a couple of hours every day while the kids were in school, and even had my Brother take orders at the night club he played at. One of my Moms stuck me with 20 unsold cases two days before money was due. Neither of us wanted to write that check.
Being cookie Mom sucks.
