We know just how unpredictable ebay and amazon can be, so we understand that even though you did everything correctly you can still find your account needing to be replaced one day. But fear not because 24vc has you covered! At any point in time you can request a fresh ip change, and there is only a one time fee of $15 per change.
So there is absolutely no risk in committing long term and the discounts you would get from signing up for annual billing are significant!
