Occasionally I find discarded items that can be resold for scrap value on my day trips or walks. My recent find didn't pan out well (get hits & misses depending on materials). I made the most of my remaining trip for walking and coin-scrounging. I don't necessarily need to keep doing this but it's changed from me needing it for buying essentials to adding to my savings. I know, it's not the best way to build up savings but it doesn't hurt to collect spare change while I go out for shopping or exercise, especially while waiting for your next deposit.
