If you hadn't noticed Amazon's Prime Day sale is well underway, and, if you head over to our best Prime Day deals page, you'll find deals saving you hundreds on televisions, smartphones, fitness watches and more, but, Prime Day isn't just about those big-ticket items…

You can also pick up little, everyday items, that aren't quite as sexy as a new curved gaming monitor but will still save you money in the long run.

We're talking about batteries, dishwasher tablets, condoms and nappies, all things that you can buy in bulk to save money, but wouldn't necessarily think about buying on Amazon Prime Day.

So, whether you're doing a bulk order to fill your pantry, or looking to add a few extra deals on top of your existing savings on a large piece of tech, these are the things you should be adding to your Prime Day basket.

Dishwasher tablets (opens in new tab)

Okay, this is an obvious one. Dishwasher tablets are frequently some of the most bought items on Prime Day and Black Friday. It makes sense to bulk buy these everyday items while they're on offer, rather than wait until you've run out and buy them at a marked-up price in a supermarket. Get sparkling clean dishes at a fraction of the cost.
