I had a Penguin salesman here a couple weeks ago give me a quote on replacing 9 windows, 1st quote was over $12K, told him we just bought the house and didn't have that kind of $$$ to spend at that time, he says, wait, let me recalculate this, couple minutes later he gives us a quote of $10800, I told him we had to think about it and we would call him back the next day, he reluctantly left then called us an hour later with a $10K quote and he forgot to tell us this would be interest free for a year. All of this after telling us he doesn't work on commission. We plan on replacing these windows with income tax refund but I'm definetly getting 2 more quotes before I pull the trigger on anything.
