At the beginning of this year sometime, a young girl came to my door and started out with "Hi, My name is so-and-so and I live on the other end of Your Avenue. I'm Debra's daughter, and you've probably seen her walking our dog. Anyway, my class is selling magazines to raise money for a trip to London ... these are the magazines I'm selling (and she whips out a brochure."
Now, I have a 78 lb. German Shepherd Dog that goes absolutely nuts when anyone comes to the door, so I open it a tiny crack and explain that I can't open it anymore because of the dog. That being said, I asked the girl if she could leave a brochure with me so that I could look it over and order directly on a website. She said no; I told her I couldn't help her and I wished her good luck on her fundraising.
A few days later, a co-worker of mine tells me that over the weekend, two young ladies came to his door telling me they were selling magazines door-to-door in his neighborhood, raising money to go to a trip to London. WTH?! Same as in my neighborhood?
Apparently, this is completely a scam. They have no license to sell door-to-door, they can't give you their school's name, they want to be invited into your home so they can scope out the goods, etc.
And just recently (like, two weeks ago "recently"), I had a young man come to my door with an accent, claiming he was from Israel, and that he and his friend wanted opinions on their oil paintings. ???????
I told him I'm not interested, wished him good luck, and got right onto Google to see if this was another scam. Yep, sure was.
I don't know anything about the "business" you are asking about, but I figured it wouldn't hurt to share my similar experiences with you. I am very cautious about these kids selling door-to-door and will contribute my purchases to people at work whose kids are selling something (cookies, wrapping paper, etc.).
Good luck to you :)
