It's a fact of life that prices will fluctuate, but many retailers now offer price adjustments to take a little bit of the worry out of making a purchase. SavvySugar has compiled a list of 10 retailers that do price adjustments and matching, as well as the time frame to claim a lower price.

Scoring a better price on a past purchase is nothing new, in fact the now-defunct Circuit City used to offer a 60 day HDTV guarantee before it closed up shop, but in the past few years the number of items you can get a price adjustment on has greatly increased.

In its survey of price adjustment policies at retailers, SavvySugar found that many are offering a generous 14 day period to get money back if the price has dropped. Some retailers are even going the extra mile and adjusting for lower prices at competing stores. On top of price adjusting appliances and HDTVs, the SavvySugar article points out that you can even get price adjustments at many clothing stores and on Wal-Mart purchases!My favorite retailer for price adjustments and matching is Sears, due to its 30 day price matching and adjustment time period. As an added bonus it will even match online retailers, including shipping, and give you an extra 10% of the difference!

Now that we've added another step to becoming a bargain shopping pro, how can you make sure that you stay on top of price drops for the 2-4 weeks after making your purchase? One of the simplest ways is to look at the weekly flier in your local paper or at the store's website, or stop in the store once or twice after you purchase. Any deals found online via a deal website are easy to check up on by monitoring the deal page for the next few weeks.

Perhaps the easiest way to track lower prices is to use an online price tracker like dealalerter or Priceprotectr, which will track price drops at hundreds of stores for you and let you know when a price drops below what you paid.

However you plan to do it, the quest for the best price doesn't end when you bring a purchase home.
