As others have said, print out the webpage and bring it with you. But...keep it in your back pocket. We did our homework prior to going to the dealership. The online price was $5,000 less than the salesman quoted us (he was really playing the role of the martyr..."I can work with management and can possibly get a thousand dollars off the price." - sheesh, don't do me any favors).
Anyhoo, we kept our mouths shut until it was time to talk numbers. I asked him for his best price and when he gave us the high figure, we informed him of the online price. His look of shock was laughable but he did go online to verify this. Funny thing, when he logged onto the site, it turns out the price had been lowered an additional $2,000. Turns out the owner had stopped by that very morning (I saw him walking around the lot) and dropped the price as he wanted to move this particular unit. It worked.
badge2283 - may I ask which dealership? We dealt with RV Direct in Orlando but live down the coast from you in Cocoa. Always good to know of a quality Mom & Pop Dealership. Thanks.
