From time to time we allow purchasing of items not in stock. If listed online as out of stock but backorders are enabled then we expect that the delay would not be significant.
Where there will be a delay we do not allow backordering and instead we ask that you enter your email address into the waitlist provided on the product page for the item listed.
We often have orders where small items or optional parts are out of stock. We may hold back the delivery until these items come into stock or we will part ship and send the backordered items as soon as they arrive in.
Generally we try to stock as many items as possible listed online and for some items we can list stock numbers.
For any outstanding items please contact us via the ticket system or email support quoting your invoice number.
