Query: Great seller, very responsive

OK, this isn't a high point for Danny Devito or Matthew Broderick (you'd have to go back to Wargames for Broderick's cinema high point), but my daughter loves this movie. Two minutes after I placed the order I had a question of the seller, and he/she responded to my question within five minutes. Spot on.
