How do they do it?

Bargain shopping is a passion of mine. There are many people who think that I am extremely good at it. The truth is that I really am a novice compared to many people out there. I don't really know how they manage to find the deals they find. My suspicion is that they have a barcode scanner they take with them to the store. For example, someone once posted on a website I follow about play ground equipment they found for 90% off. There was no sale sign in the stores and nothing to indicate this unbelievable deal was going on. Who shops for swing sets in February? Well, I did after they posted that sale and got my son a $500 play set for $50.00! This has been my best sale to date but I really can't take credit for it. All I did was read a website to find it.
