Do you have used smartphones, fitness watches, smartwatches and other gadgets at home that you want to finally let go of? If so, then don't throw them away just yet because these can be worth hundreds of dollars -- and we all know that during these trying times, cash is king.

Fortunately, there are ways to help clear your home of used electronics in exchange for cold, hard cash without having to go to a pawn shop. One of these is through the following online services that will negate the need for you to find or negotiate with potential buyers all by yourself:
