I can't speak for the typical "bidding" system, but I can speak about the new "Greentoe NOW" system. I was just searching Google for a built in BBQ Grill when I spotted a price that seemed too good to be true, almost entirely by accident. I nearly skipped right past it, but I decided to do some research. Mixed reviews about the results, but it was definitely a real website so I decided to give it a shot and placed my order. That very same evening I received an email confirming my order was received. I was still skeptical but hopeful and excited. Long story short I got my grill 2 days later and saved a total of $1400.00 price, tax and shipping on a grill that every dealer said they couldn't deal on!
