Configurable options slider free mimimun quantity.
Actually the Configurable options quantity slider only allows to have a quantity to start from but not to bill from.
For example, if you configure a Disk Space to start from 5GB and bill each GB 1 Euro, the customer will be invoiced 5 Euros per default.
What if I wanted to offer the first 5GB? I will need to configure a coupon code, a bundle or use a dropdown list :( ; which is really not a good commercial ergonomic.
