After recently writing about CouponWinner and Rather-Be-Shopping in previous WalletPop posts like this one and this one, I've just learned about another online coupon site. I'm starting to lose track of all of the other ones out there, but I have come to the conclusion that if you shop online without first checking to see if there's an online coupon that can save you money on what you're buying, then -- well, you probably have more money than me.

My latest discovery is CouponChief.com. The spokesperson dropped me a line to let me know that they've just relaunched their site with some new features and "an easy-to-use design."

Maybe those words are code for not all that flashy -- because I was visually underwhelmed when I first glanced at the site, frankly. That said, dig a little deeper, and you'll find plenty to look at and like. Besides, bargain hunters go to coupon web sites for substance and not sizzle, and CouponChief.com delivers. There are plenty of coupons here. They also are trying to foster a coupon community with their blog (they need to get up more posts, though, if they want members to start commenting), and they're encouraging members to upload coupons themselves.

Certainly one good reason to bookmark this site along with any other coupon sites you visit is that, to celebrate their relaunching, CouponChief.com is giving away an Apple iPhone 3G every other day for two months, beginning July 11. Users are automatically entered into the contest whenever they forward coupons along to friends and whenever they upload coupons onto the site.

So if you're shopping online, check out CouponChief.com and in general, you should get in the habit of checking out the coupon online sites whenever you're making a purchase online. In the words of Mick Jagger and Keith Richards, "you can't always get what you want, but if you try sometime, you just might find you get what you need".

(Not many people know this, but I'm pretty sure that Mick Jagger and Keith Richards wrote that song after a shopping binge.)
