It might be early, but Black Friday desktop PC deals have begun. Some retailers have already launched early deals on everything from home office computers to gaming PCs to all-in-ones. What’s more, many retailers are offering price protection so you can make your purchase now and rest assured you’ll end up with the best price.

Early Black Friday deals have landed at Best Buy, so I've been scrolling the full sale all morning. While gathering all the biggest discounts, though, I noticed a problem. I price check every deal I find, to make sure it's the lowest on the web, and have found that Amazon has snuck into Best Buy's party this week.
