Down-river.net is the missing search engine for Amazon's extensive Warehouse selection -- mostly returns and whatnot, basically new but open box. Items are shipped from Amazon warehouses via Amazon Prime and have the full range of Amazon benefits: fast delivery, easy returns, etc..

Down-river.net simplifies browsing the Warehouse, trimming out all the distractions and sponsored products, random low quality brands. All wheat, no chaff.

I mostly buy used stuff from REI or Patagonia. I originally built down-river.net for my own use and use it somewhat regularly to grab stuff for my family's outdoor adventures. Hopefully other folks find it helpful as well...
