UNDATED -- Black Friday is full of hot deals, but the day of shopping can be overwhelming.

The National Retail Federation says holiday sales will likely bump up about four percent this year, which is around $679 billion dollars. This means more shoppers and more people trying to snag those holiday gifts.

If you want to get the most bang for your buck, check out these tips from the Better Business Bureau. Look for Black Friday ads ahead of time and do your research. Many retailers roll out their specials before the holiday.

Learn about the store’s return policy because companies are not required to give you your money back, but they do need to have their policy displayed near the cashier.

It also pays to compare prices at different stores to make sure you’re really getting a deal. If you can’t find the right present, you can always buy them a gift card, and of course, steer clear of online ads too good to be true.

If you miss a sale, keep in mind that there will be more chances to save through the holiday shopping season.
