LIKEtoKNOW.it is one of my favorite shopping tools! Whenever someone I follow on instagram posts anything from a cute pair of sandals to a fabulous rug, all I have to do is like the image and an email comes to my inbox with a link to the source (as long as that instagrammer uses LIKEtoKNOW.it). Signing up is easy here. You can even select how often you want to receive emails - asap, daily or weekly. I like to receive them asap! This is so much easier than asking someone where they found their pillow and waiting for a response and possibly forgetting to follow up.
If this is still confusing, please feel free to email me and I will try to help. Have a great day!
