This is not an advertisement, that is why I blurred the brand names because I won't really recommend and brand name. it is up to you to make brand name comparisons.
What are the coolest things you had purchased online?
Here is mine:
Rechargeable USB batteries.

I hate it when my remote control or wall clocks battery got drained. Buying multiple AAA batteries can be annoying.So I found these rechargeable batteries that you can charge to your USB ports. I don't need to buy new batteries again since I can recharge these batteries.
Freeze dryer

Whenever I harvest fruits from my orchards, I realize that I cannot sell and eat all of them. So I purchased a dryer so I can use them for certain recipes or just have a snack. A freeze dried food can have an expiration of 10 years as long as you place it in an airtight container. I am ready for the apocalypse!!! I was able to make sweet potato flour from sweet potatoes. I freeze dried them and powdered them in blender! You can preserve food without chemicals! You can have crispy fruit and vegetable chips.
Flavored inhalers-

I love inhalers, I hate having a clogged nose and inhalers gives me the instant relief. I know most people uses Vicks inhalers. Look inhalers will not cure your colds or sinusitis but they made my life easier. You still need medication to cure your sinusitis of colds but yeah Inhaler is a great escape from clogged nose.
One complain I have with inhalers, they all smell the same. They are all Mint or eucalyptus flavors. Online stores introduced me to flavored inhalers, They infused mint or eucalyptus to herbs,flowers and fruit flavors. I love lemon, lavender,orange, Himalayan Pink salt and blueberry flavors. No I am not an inhaler addict, I just use them when my nose gets runny. I love the diverse flavors I can buy online, some of them are cheaper than Vicks.
