Very interesting concept. Thanks to Niche Retail's Advanced URL Deployment System, it's always pretty clear what's for sale on a given site: JoggingStrollers.com, EliteCarSeats.com, ReturnsForSale.com, etc.
You may recognize the first two from their flashy advertisements on Daddy Types. That last one's new, though, and it has a twist: sure, it resells strollers and other gear that has come back to the store [each piece has a condition report and photo details where necessary, they also have closeouts]. But the already-low price for each item drops by 1% each day. The longer you wait, the cheaper it gets! Until, of course, it's gets just cheap enough for someone else, who snaps it up while you were rolling pennies.
