The 9 Best Buying and Selling Apps

The Best Buying and Selling Apps

I have a confession to make: I love keeping my kids’ things. I mean EVERYTHING. Baby clothes, baby toys, babyeverything. I used to have a hard time selling or donating these items simply because I attached a memory to them all. 

Flash forward a year later and as closets started to burst and my wallet grew emptier from our transition to a one-income household, it was time for a change. 

Being the innovative person that I was, I knew there had to be a way I could clean up and make money from this baby-hoarding habit I had gotten myself into. 

Turns out, there was no need to invent anything. Some quick thinking and a little Googling, and I landed among a plethora of selling apps! 

I’ve found that these selling apps can be faster to use, and as a bonus, give all of my unused, once loved “stuff” another platform to shine on. 

The more exposure your items get, the bigger the audience, the better chance you’ll have to sell everything and presto – money for your next vacation!

Whether you’re looking to make space, get rid of things you don’t wear, or save some money for your next purchase, below is a list of 9 of the best buying and selling apps you can easily download and start using today.

Clothes gathering dust in your closet? How about a playroom filled with unused toys? Grab your smartphone or tablet, snap a picture, upload it, and get selling in all of 60 seconds!
