Evil competition

Our Amazon store is a great success story for us. However, others are starting to sell the ball on Amazon as well. One company in particular seems to be fairly awful. While we're working hard to keep our negative feedback as low as possible (it's currently about 4%), this company just doesn't seem to care. Their negative feedback is currently 24%. They are selling a number of other UCO products as well and most of them seem suspicious. The prices are too low, the descriptions are strange (incomplete, etc.). I'm debating sending a note to Amazon, but this company may self-destruct anyway with their weird pricing and terrible service.
