If you have let a Groupon expire, don't throw it out. While the business you bought the coupon from may try to say it's worthless, there is a way to get your money back.

Half of the daily clients at the Get Nailed nail bar in North Vancouver are Groupon customers, thanks to a big online coupon discount on manicure-pedicure packages.

Owner Adrienne Greenwood says its 6,300 Groupon customers may face delays getting an appointment, but she vows to honour them all before they expire next March.

But what if it can't service all those coupon clients?

Tatianna Chabeaux-Smith of Consumer Protection B.C. says it's up to each individual business.

"The law is silent on the value of a Groupon or online coupon once it expires, so it would be up to the discretion of the business as to how much that would be worth," she said.

Some B.C. businesses have turned away Groupon customers with expired coupons, but before you toss that online voucher, there's hope.

Although consumers in B.C. are not protected by law when it comes to Groupon vouchers, the American-based company says it's willing to stand by its corporate promise.

Groupon said if "there's ever any issue with a merchant or on our end where you're not able to redeem your Groupon, you can contact us for a full return, and we'll either give you your money back, or we'll give you back site credit," said Director of Communications Julie Mossler.

Greenwood is promising to honour all Groupons sold, but has a warning for people buying discount coupons online.

"If there's already 2,000 of a service-oriented business sold, you're probably going to have to get in line. It's a coupon," said Greenwood.
