Excuse my ignorance... I'm more a manufacturer than anything, and I don't do typical retail items. I was wondering a few days back, when I found a promo code to use on a shoes site... What is the benefit of doing this? I mean, I can understand maybe sending out unique promo codes to select customers, or doing something right on the site that states you have to put in a certain code... But what is the strategy behind having codes that you do NOT display on a site, yet you can find them on any decent coupon site? Are they just going after people who are smart enough to search for a code, but otherwise wouldn't buy stuff? I easily found a code for 35% off, which is pretty significant. Obviously the sales sites must know this is happening, as it would be easy enough to change daily.
