NEW YORK (MainStreet) – The Gap is offering a coupon code for $25 off purchases of $50 or more. There’s just one catch: You have to give the company your phone number.

Rather than just putting up a printable coupon, the Gap is making you go to this website and enter your mobile phone number. The retailer will then text you a coupon code, which can then be used only in stores. Purchases of at least $50 will be discounted by $25.

Of course, we have no way of knowing what the Gap will do with your number, and it’s quite possible the retailer will never text you again. But we’re a little wary of giving out our phone numbers to companies. If you sign up for an e-mail list you can easily ignore or filter out the subsequent e-mails, but it would be a lot more annoying if you start getting text messages about sales and promotions.

Still, if you don’t mind the prospect of the Gap sticking you in its Rolodex, this looks like a good deal. It’s only valid today through Wednesday, so act fast.
