One unpleasant shopping experience I remember was at a sportswear website called Fabletics. As part of the VIP membership program they promise you can save up to 50% off regular pricing and earn points. They also say that VIP membership works flexible. I started like a Vip Member on January and lasted on March. Every month I was supposed to choice if I wanted to shop or not. You had to “skip the month” before the 5th of each month if you didn’t want to afford it. In case you didn’t choose it at time, they would charge 49€ per month in your bank account.
At first it seemed easy, but the true? I only bought on my own one outfit, they charged me two more (each per month) and I kept monthly angry until I got unsubscribed from the Vip Member list!!
