Hot rock spa treatment

Recession Spa
You've likely heard that beauty schools offer free or seriously discounted haircuts by students under teacher supervision. At Aveda Institutes, for instance, you can get $15 to $25 cuts (AvedaInstitutes.com). You might also try massage schools: The American Massage Therapy Association lists institutions on its site, searchable by state (AmtaMassage.org/amta-cos). Steiner Education Group's chain of accredited massage schools has 17 locations, from Las Vegas to Miami, and offers 50-minute massages by students, usually Saturdays or Sundays, starting at $25 (SteinereEd.com).

Car insurance

Insurance Relief
Most homeowner's premiums are neatly incorporated into the mortgage payment, so consumers don't consider reviewing them. That's a mistake. If you shop around and find something better, call your insurance provider and ask what they can do for you, suggests Ellie Kay, author of Living Rich for Less. Certain improvements (installing a security system or a new roof; adding storm shutters, smoke detectors, deadbolt locks) and even a change in habits (quitting smoking) could qualify you for lower rates. You can typically expect about 15 percent savings, Kay says.

Play the Loyalty Card
Find out if your favorite lunch spot, coffee joint, or hair salon offers a loyalty card or promotions through Facebook. Così sandwich shops have a CosìCard, which provides a free reward after ten purchases; customers who become of fan of Champps Americana on Facebook get a coupon for a free burger (participating locations only). At my local nail salon, a manicure is $10, but with the card, every tenth one is free.
Car

Deal on Wheels
If you need a car but can't swing the down payment, you might consider taking over someone else's lease through SwapALease.com or LeaseTrader.com. These websites match leaseholders with people who need cars. The customer must submit a credit application, and once approved, she assumes the rest of the monthly payments.
Subway

A Cheaper Commute
In March, the maximum tax-free transit benefit for commuters who use public transportation increased from $120 to $230 a month. That means commuters in the 25 percent tax bracket would save an extra $330 in a year. Contact your HR department to see if your company is registered and to obtain an application.

Don't Get Taken for a Ride
Talk to your auto insurance provider and ask if there are discounts available. Many companies offer lower rates if you have an anti-theft system, a garage, if you're a non-smoker, or if you're between ages 30 and 60. Drivers willing to spend a Saturday afternoon taking a safety course can fax their certificate of completion to their insurer; many receive about 15-percent off their premiums.

Mailbox with bills

Scrutinize Your Bills
You might find anything from unrequested subscription renewals on your credit card bill to accidental double charges from retailers. Looking at my bank statement, I noticed I was being debited $15 every three months for an insurance policy I cancelled three years ago. Check the phone and cable bills, too; There's a common practice called cramming in which your own comapny or another service provider adds charges to your bill that are vague, misleading, or unauthorized, or you're billed for services you didn't receive. — Anne Kadet
Texting

E-mail Your Text Messages

For Verizon Wireless customers, the address is the number@vtext.com; for AT&T, number@txt.att.net; for T-Mobile, number@tmomail.net; for Sprint, number@messaging.sprintpcs.com. — Anne Kadet

Get First Dibs on Sales
Clothing stores typically mark down their inventory on a certain night after they close the store—say, every Tuesday evening. For the best selection, ask a clerk which day is markdown day and show up first thing the next morning. — Anne Kadet
Piggy bank and cell phone

Check the Price By Phone
There's a way to find out—as you're standing in the aisle—if the store sale price is a good deal. Call 1-888-DO-FRUCALL and type in the bar code number of the product in question. Frucall's free service will tell you the range of prices that online retailers, including Amazon.com, charge for the same item. If you own an iPhone or an iPod Touch, the Amazon app does the same thing. — Anne Kadet

Use Your Flexible Spending Account
Only a third of eligible employees take advantage of FSAs, which allow you to take a teax deduction on medical expenses your insurance doesn't cover, including copays and therapy visits. A person making $35,000 could save $200 on taxes. — Anne Kadet
Vegetables

Farm Fresh For Less
If you're committed to staying organic, Community Supported Agriculture programs are cropping up all over the country. Pay $20-$30 (some require minimal community service as well) a week (or do a $10 half share for 1-2 people) in exchange for fresh veggies straight from the farm. Check LocalHarvest.org to find a CSA near you. A family of four that spends about $10 per person on produce a week could save as much as $80 per month. — Dorothea Hunter
Art museum

High Art, Low Prices
Many museums offer free or discounted admission at particular times. In Manhattan, the Museum of Modern Art is free on Fridays from 4 pm to 8pm. Admission is free to the newly expanded Art Institute of Chicago on Thursday from 5 p.m. to 8 p.m.
