Hello! This is from the JustFab team. We know that this question was raised over a year ago, but we would like to address it.

No, you will not be charged as long as you do not place any initial order with the introductory offer as a VIP member online.

Their plan is something you get stuck in. It's a business model for making money so it's quite brilliant. If you don't opt out each month, you get a charge which banks in your account for credits. Each one is 39.99 towards purchases. If things are more expensive, you have to pay cash in addition to using a credit and for sale things, you still have to use a whole credit even if it's only $10. They claim that the $10 is a sale available with no other offers (which includes VIP's very special price of $39.99-[actually, that is not a cheap price], so you pay the regular price of $39.99 + via one of your banked up credits, or you pay cash and get the special price. Sometimes you cannot return clearance. You do get free shipping with VIP membership. I have never had a problem with making a return or exchange in 7 years except they run out of my size often. It's been just as easy as Amazon returns with the exact same requirements BUT, if you want a refund you will pay restocking fees which may include S&H. The way to avoid that is by having them issue you credits. And this is why after 7 years I can't seem to get out but I am in the habit now of "skipping the month" as to no get any further credits. I don't want more credits, I just want the membership for the great sales. That's the way to do it! Some stuff is super cheap but others are good enough and some are surprisingly good. They have a great selection of stuff that I get compliments on all of the time.
ONe time, my stuff was shipped to the wrong address in my account ( to my daughter's house in California) by my own fault. Worse yet, she didn't live there anymore. 3 pairs of boots were delivered and enjoyed by somebody. Just Fab gave me back all 3 credits which they certainly did not need to do. Website is sooo slow! Phone agents are to rehearsed and annoying, trained to say, "yes ma'am I am sorry to hear that this didn't work out for you, blah blah..."
I was kind of annoyed with them and started reading reviews and I realized that most people just don't understand or aren't cut out for this program. I been treated so well and felt I had to share that I haven't had any of the complaints I have read in this forum. You do need to be responsible as with all online accounts, and reconcile your account on occasion. I don't think they are deliberately trying to rip people off (beyond what their business model intends & we agree to).
