The Whistler WBU-900 Digital Wireless Backup Camera is on clearance at Walmart for just $30! Original price was $249.95! This is a YMMV (your mileage may vary) deal in that you will need to find this in store. They haven’t marked it down everywhere, so prices will vary. If your area hasn’t marked it down yet, that’s good news because it means there’s still some in stock and you can watch for it to be marked down in the near future!
