It is anticipated...
I'd like to take a moment just to clarify our motivation on pre-listing products.
We pre-list the items so people can order them, if the price goes up the customer is advised of this before the goods are charged and invoiced. If the customer does not wish to proceed as the price has gone up their full deposit will be refunded.
If the price has gone down we will invoice at the lower cost.
Camera estimates are hard to do 100% accurately as the cost in other territories is not always relevant in the Australian market.
The idea of that whole system is to allow people who really want the product to get in early and avoid lengthy waits.
