Yes it's a Custom Standard order. I certainly hope that there is a price difference between the original order and the revised one.
You're saying that the pricing on these things change from month to month. So the final price when it arrives may not be what I was originally quoted?
They won't raise the price once you've placed an order. It's that you could place the order then a month later someone else could order the same thing and pay less or pay more. Like buying anything, the price can fluctuate but they won't raise it once you order. That locks in that price good or bad
