Most people will probably forget that the Amazon Warehouse exists, I know I did, but it is a great place to get some discounts on products that aren't technically new - but are still in sellable condition. In case you hadn't noticed, Prime Day is currently going on and the Amazon Warehouse isn't being left out.
For the duration of the sales event (now until midnight tomorrow) Amazon will be knocking 20 per cent off all Warehouse purchases - regardless of what those purchases actually are. Naturally, being Prime Day, you'll need to have an Amazon Prime account to qualify for the discount, though you can always grab yourself one of the free trials Amazon basically hands out like the sweet shop owner in Willy Wonka.
You may not notice any immediate change in the prices on site, and that's because Amazon will only deduct the final 20% when you check out. That means it's up to you to figure out what money you'll be saving and whether you actually want whatever it is you're looking at.
