They hit me up out in Lancaster in the mid-90's. Story was they were delivering to the Sam Goody down the street, and the warehouse loaded too many into the van, so they wanted to make some cash. I was a broke student at the time, so no deal...

If I remember correctly, a local news station did a story on them, it was a company with a strange business model selling speakers that looked and had names similar to real brands.

There is even a wikipedia page on the White Van Speaker Scam
