I use PCBCART.com but the turn around is a little slow. I placed an order 3weeks ago and still waiting but it is more than Half the price of the NZ counterpart.
Have you checked your spam folder?
I think you can view the status of your order on there website to.
PCBCart have always been quick for me.
After i submit my order they always respond within 4 days with either; Questions about the design or Confirmation that they have started manufacturer.
Once they start manufacture they always ship within the lead-time that I've payed for (8 or 10days).
Shipping is normally 1 week or so.
