I just don't think it is a very sincere selling tactic to mention the six others you have by someone else. If you've worked with this designer as long as you have, why didn't you discover years ago the quality that you are trying to sell us now? Its like these clowns on other networks that say they got a ticket because they didn't buy the radar detector they've been airing for years. Totally fake, fake, fake.
If she had worked with this designer as long as she claimed, why didn't she know the quality she is trying to sell to us, instead of buying six others from someone else? Totally insincere, it just backfires.
