Dumpster diving for coupons is one of the ways that some extreme couponers get more coupons. That’s right they dig through dumpsters for discarded papers. However most don’t dive into trash bins but instead dive into recycling bins full of newspapers. Is this legal? Well it depends. Check with your local city, county or state laws to see if it is allowed or if the recycling bin is located on private property ask the property owner before you dive.
