While this may seem like a no-brainer to many, some individuals (i.e. regulators and various economists) suggest that because perfect information does not exist for all market participants, the market must be regulated. The reality of the situation seems to contradict this paternalistic urge and several entrepreneurs have specialized (exploited, if you will) in collecting our favorite specialty pricing schticks: coupons, rebates and cash-back (oh my).
For instance, the techno-enthusiasts over at ArsTechnica found a whammy of a deal regarding a 50% coupon for certain Dell laptops ($750 off a $1499 product). It starts tomorrow at 8 AM CST — last time the inventory only lasted for a couple of hours. Additionally, FatWallet.com displays hundreds of coupons and rebates for retailers (like Staples) as well as cash-back options from the likes of Target and Nordstroms.
