Shoe Dazzle/Just Fab users??!

So I REALLY wanted a new pair of over the thigh boots for thanksgiving & what not. I decided to sign up for Just Fab, but just the part where it says you get your first pair for $10 & you have an hour to choose.

I didn't like any of the boots there, so I went to Shoe Dazzle, signed up & had an hour to pick $10 shoes. I found an amazing pair & paid for them. However, I DO NOT want to be an monthly member & have to pay every month. My shoes have not come yet, so if I cancel my membership, will I still receive the shoes??? Or do I have to cancel after my shoes arrive & will I be charged a month fee?
