How does price matching work? Here are the policies from top retailers.

We're all trying to shop smart, especially during this time of the season. As soon as Halloween passes, holiday commercials blare upcoming sales from major retailers, nudging viewers to get their holiday shopping over and done with.

Before running to the nearest Target or Walmart for the annual Black Friday rush, you might want to check their return and price matching policies.

Here are five price matching policies from Black Friday big shots.

Target's price match policy states that the store will match in-store prices of identical items from Target.com and a list of select competitors including Amazon, CVS, Best Buy, and Wal-Mart. According to Target's corporate website, purchases from Thanksgiving through the end of the following week — this year that runs from Nov. 24 until Dec. 3 — will not qualify for match or adjustment.
