It's a reasonable question. You can save a lot with a display model. We bought a $500 SONY TV once for $150 at Walmart because it was the display model and the last one. It was on sale at the time for $300.
We bought a $100 rocking chair for $20 at the same Walmart because it was the demo model. They can't sell the demo models at full price because they've been handled.
Now only if Lowe's hadn't been so unreasonable about giving me a discount on that display model lamp I bought at their grand opening
