Gerri Willis gives tips on how to save on air travel, gyms, clothing and even more by bartering.

NEW YORK (CNNMoney.com) -- If you're worried about getting laid off, there are companies out there dedicated to helping you overcome your spending anxiety.

Let's look at the details of JetBlue's Promise Program. You can get a refund on your flight if you've booked your trip with JetBlue between Feb. 17 and June 1 this year and you were laid off, by no fault of your own on or after February 17.

To get your refund, you will have to put the request in writing two weeks before you're set to fly. The program does not cover corporate or group travel bookings. For more information, go to jetblue.com/promiseprogram.

Gyms are also trying to make it easier for you to join or keep your membership if you were laid off. Some YMCAs for example have waived sign-up fees. You may qualify for a reduction in membership costs or your membership may be extended at no charge on a case by case basis. To see what offers may be available at your YMCA, visit your local branch.

Even clothing stores are marketing to the unemployed. JoS. A. Bank Clothiers announced a program that offers a full rebate on the price of a suit if you lose your job. The good news is that you can keep the suit.

And when you're out of a job - saving money is at the top of your priority list.

Here are some places to go on the Web if you want to exchange items or barter.

Check out Freecycle.org. This is a community recycling organization where you can find things for free locally.

Swapthing.com lets you post what you're looking for and you can swap with someone else.

And finally, Craigslist.com has a barter tab where you can trade your stuff.
