dont do it. i did springmasters for the aeration crap, and that seems like the same thing. I worked 12 hours, going door to door trying to sell their product in the pouring rain. The vans are overpacked, 2 kids sat in the trunk of those white vans (its maybe like 2x4' in the back so these kids were squished together, while we had 4 kids in the backseat that sits 3, and 4 in the middle that sits 3. Nobody could wear seatbelts if they wanted too.
In the end, I made like 8 sales I think in 12 hours, like $300 for them. in return I got $40, and a 50% coupon for their snacks. I went to buy a snack and a chocolate bar was like $3, (the 1.50 ones in the store). Said your fucking kidding me and left.
I didn't have a good day, I wouldn't recommend doing it if I were you. To top it off I lost the $40 the next day.
