This is an easy way to help homeless veterans during the holidays

A popular app that connects resellers with buyers for used items just announced an initiative to help the military community fulfill the holiday wishlists of 15 homeless veteran shelters across the country.

The makers of the ReSupply app launched the holiday effort, dubbed Operation ReSupply, which will allow app users to find, acquire, and ship items from a master shelter wish list via their mobile devices through Jan. 1.

How it works in three steps:

1. Verified ReSupply users submit their donations via the app.

2. Next, a ReSupply brand ambassador matches the item with a shelter.

3. Finally, the app provides donors with a prepaid shipping label.

All the proceeds from sales between app users during this period will also be donated to the veteran shelters.

While the ReSupply app only works with veterans and servicemembers verified through ID.me, civilians who wish to participate can help cover shipping costs by donating to #OperationReSupply's Go Fund Me page.
