As of right now, nothing has actually changed. The rates are the same as they used to be.
We will be changing them within the next few weeks, but will make sure to let you know what the implications of this will be.
One quick note for when we do make the change, if you are using Auctiva checkout and our insurance option, you will not lose money when the rates change. The rate increase will be reflected to the buyer in our checkout flow, so the buyer will pay the increased rate and your "rebate" back from Auctiva will remain as it is.
