SAN DIEGO -- It's either bad parenting, or genius marketing, depending on how you feel about the green stuff.

Cell phone video shows a 9-year-old selling Girl Scout cookies out of a wagon near a marijuana dispensary.

The girl's father wants he and his daughter to remain anonymous, but says she sold 312 boxes in two three-hour trips on Wednesday and Friday.

An Instagram post from the dispensary Urban Leaf even advertised the girl will be outside.

 “We all looked at that and our first inclination was it must be a booth sale because it said until 4:00 p.m.,” said Alison Bushan of Girl Scouts Dan Diego.

The Girl Scouts allow booths sales generally in front of any business -- even dispensaries. Once they're approved, Bushan says this would have been a major no-no if the girl had a table on the door. But having the wagon off-site changes everything.

“So that's what they were doing, and they had their car, and they were walking around their community. That is right and well within the rules,” said Bushan.

As for the hundreds of boxes sold in a few hours, the competition has just begun.

Bushan said, “From a sales standpoint she has done alright, but I know that some of my friends have sold 600 boxes just on Sunday walking their neighborhood. So there are many ways that girls are being great entrepreneurs.”

Girl Scouts across the country began selling cookies last month and will continue to do so online and in neighborhoods until April.
