I dabbled. The ROI for the amount of work sometimes made the ROI feel inadequate.. but yeah ever now and then it would be a huge score. One otger thing I did was identify recalls, then stock up on those items from every thrift store near me, then take them to Walmart where they'd pay me the retail price which they then got from the manufacturer. That was a cash cow for a little bit. Walmart may have changed their policies on that now.
