remove sidebar on a salespage

I want to create two sales/landing pages on my website, and I want to remove the sidebar from those 2 pages only (less distraction).

Does anyone know how I can accomplish this?

Here are the 2 pages I’m talking about…

Thanks,
Joshua

ps. I created a second theme without the sidebar in hopes I could just assign those 2 pages to the new theme — no luck
