​If finding a phenomenal deal gives you a thrill—even a high—you may be what researchers at San Francisco State term a "sport shopper."

Not to be confused with shoppers who simply want a bargain, "sport shoppers are not looking for a deal to save money, but rather are more interested in outsmarting the retail system," explains Kathleen O'Donnell, Ph.D., professor of marketing at San Francisco State University.

Dr. O'Donnell has published research on sport shopping, along with SFSU's Judi Strebel, Ph.D., chair of the marketing department and Dr. Gary Mortimer of the Queensland Univeristy of Technology in Australia.

Just as with team athletics, sport shoppers are competitors; they don't enjoy all shopping, in fact—just the thrill of the hunt for "exceptional bargains on specifically desired items," write O'Donnell and her fellow authors in research published in the January 2016 issue of the Journal of Retailing and Consumer Services.

For sport shoppers, "every day is a treasure hunt," notes O'Donnell.

Using a combination of discounts (promo codes, coupons), credit card reward points, sales, and other strategies, sport shoppers compete against the retail system to purchase items at the lowest price possible, she says.

Does this sound like you or someone you know?  Here are four signs you may be a sport shopper:

1. You love sharing about your purchases. You also have a great memory for the details of the bargains you got; they weren't just great deals, but victories. Because you enjoy talking about your experiences, you've been able to influence others to shop at certain stores.

2. You're disappointed if you have to pay full price. Sometimes, a discount isn't enough. You prefer to combine sales and reward points to maximize your savings.

3. You're open to any option, such as buying out-of-season, if it means you'll get a great deal. You also don't mind postponing gratification. For example, if you know you might be able to buy an item you've been eyeing at a much lower price in the future, you're willing to wait.

4. You don't need to actually buy anything. This is a big difference between sport shoppers and compulsive shoppers, notes O'Donnell. While browsing, sport shoppers scope out what's in the store and its layout, find out when new merchandise is coming in, and more. When it comes time to buy, they have a strategy to get an amazing deal.
