Stock up on these essential supplies before they sell out.

Whether you're at home or on the road, it's essential to have the right supplies on hand in case of an emergency. Planning in advance by stocking up on a 3-day supply of shelf-stable food and other survival basics can give you peace of mind if you ever find yourself in an emergency situation. Rather than making a checklist for individual items, your best bet is to buy preparedness kits to keep you safe if a natural disaster or other emergency should occur. The caveat is that the convenience of having everything packed into a grab-and-go waterproof bag can be pricey.

Here's some good news: Amazon is currently offering steep discounts on kits to keep you and your family safe in a wide range of scenarios. There's no telling when deals will end, so there's no time like the present to invest in these kits while they're still in stock and on sale.

All the pieces stow neatly inside a compact backpack.

Having a roadside emergency kit in the trunk of the car is a must, and this one checks boxes for basic essentials. Inside the lightweight handled case with a reflective strip on the front, you'll find jumper cables, a tow rope, a safety hammer with a belt cutter, and other tools.
