Its amazing. for less than $50 a month you get a pair of heels a month! They ask you some short questions and then show you heels based on your answers! Once a month they show you 3-4 pairs based on your interest, and you pick, then they send them to you, you don't pay until you order the shoes, if you don't want heels that month, you pay nothing, I think its ran by kim kardashian (boo) but I must say she did a good job with this site.
try google shopping online. you can actually put what price that you want to pay UP TO and toggle different catagories. also using different words in the search engine will bring up different results - not only that you can shop specifically for shoes that have a free shipping option too
