You have the "snake oil" salesmen in EVERY trade and hobby. I've seen a builders trick - put a brand name window in the kitchen of a new construction house - leave the stickers on it. The rest of the house has the knock off window version. Of course we know every house is sold by the Kitchen design which will appease the little woman. "Look honey, it has "Brand X windows" --- SOLD. Women's clothing stores placing size 8 labels on their size 12 clothing. You can bet they will have a following to, talk about trim tag fraud !!
