Several retail web sites have been designed to specifically point shoppers in the direction of a good deal, USA Today reported Friday.

Before clicking "buy now" shoppers at retail outlets that specialize in finding deals first check out the coupon code Web site, to ensure a deal is possible.

BradsDeals.com has a staff of eight searching for discounts and found 2,400 coupon codes in a recent week to pass on to shoppers. RetailMeNot.com had 71,000 coupons posted from 13,000 different merchants recently, the report said.

At RetailMeNot, shoppers submit 200 to 300 coupon codes each day, the site's owner Guy King said.

In turn, RetailMeNot found its users averaged a savings of $29 based on the average purchase price of $151, the report said.

Shoppers might also try Currentcodes.com and CouponCabin.com when searching for current deals.

Be advised, USA Today reported, shoppers should still compare prices and include shipping costs in their math, when shopping online.

Shoppers can also try bundling several coupon codes together for better deals.

"Always worth trying," King said.
