To add my free snapchat:

On computer: Grab your phone or tablet and open snapchat! Hold up to your screen (as if to take a photo), make sure snapcode is clear and in frame, then press your finger to your screen over my snapcode to add!
On mobile: Screenshot my snapcode then go to "Add Friends" next hit snapcode, then your photos from your phone will show up and my snapcode should be on there! Select photo and then add me!
