Has been a long time since we've been dumpster diving, but used to do it regularly. Went to dump our trash in town one day (last year, maybe?) when the wife spots something and calls me over. It's a new-in-package wireless headphone; IT model #: ITHW-858B. It was in the store bag along with the receipt. It had been opened, but everything was there and very clean - as if unused. The unit won't work on battery power, but works awesome with the supplied AC adapter. All cables and instructions included.
Used to get all sorts of racks and shelving from store dumpsters. Books, magazines, ...most of the stuff I can't even remember now. Still find magazines in the paper recycling bins - lots of older issues we have never seen, as well as often finding current, on-the-newsstand issues! Have found magazines we never knew existed. Lots of times we find where people are getting rid of their back-issues collections. Piles and piles of the same magazine, month-by-month, sometimes people still leave them in plastic grocery bags, which you're not supposed to do.
One time long, long ago, we went to town for groceries. As we were leaving, we stopped to notice this huge dumpster at the end of the store crammed full of food. Almost everything imaginable, but mostly MEAT!!! We had 6 hungry dogs at the time, so we loaded up the truck with all we could keep frozen and headed home. The dogs had belly aches for several days.....and LOTS and LOTS of POO!! Ever see a gluttonous dog be given a small frozen pizza? It lasts about 3 seconds. Along with the meat were bags of still-frozen chicken breasts, some seasoned some natural, lots of beef meatballs, etc. That was probably our best-ever dumpster find. Yes, as they were still frozen, we saved to eat the hard-frozen meats that we wanted. We'd thaw completely, do the sight and sniff test, then cook it up and see what it was like. ...Probably shouldn't have admitted to that, but we never once got sick, and it took us close to 4 months to use just the meat we kept for ourselves. Come to find out, the power had been out in the store for more than 2 hours, so the store dumped all the food and collected the insurance. Think about it - meat products in a grocery store after closing time, the power goes out for 2-3 hours, food is still perfectly frozen. Was VERY hot summer day, but meats were still hard-frozen when we got home.
