It is moving. The ones at the top marked "Ready to Assemble - Payment Required" are waiting for payment. If you look at those with a status of "Bench" or "Testing" and others, they are the ones presently moving through the queue.

Before the internet frenzy, Decware orders would be built, then you'd be contacted to pay the balance before the amp was shipped to you. When these waitlists grew, there were many orders being built where the purchaser failed to pay.

So now, you pay a non-refundable deposit and wait your turn. When your order nears the top of the list, you are contacted to pay the remaining balance. If you don't pay within a determined period of time (I believe it is 30 days, but Decware can confirm that), your order is cancelled.

This process continues until they have a paid order, and, parts available to build.

The list is moving. As has been suggested in other posts, it is recommended to pay your order in full before you are even contacted, because quite simply, this is a business that fulfills paid orders.
