Payment methods.	UK banks unfortunately have high charges for accepting currencies other than UK pounds - these charges would have to be passed on. The best way is to send an international money order in POUNDS STERLING. Please send a cheques or money orders made out to Mr Gareth Connor. NEW You can now send money to us by Paypal. Send to the email address above. We regret we do not offer credit card facilities at present. With present postage costs, shipping outside of the UK (typically to the USA, Canada, Australia, New Zealand, Europe, and Africa) would be an additional £5.00 (airmail) per pair of amplifier PCBs or per Precision Preamplifier. Costs for multiple PCBs are quoted on an individual basis. For UK orders, the cost of the PCB(s) includes carriage inside the UK. Orders are shipped as soon as the payment has cleared. We advise by e-mail when your payment arrives and on the day of shipping the PCB(s).

Remember that the Load Invariant and Trimodal amplifier PCBs are priced singly; two PCBs are required for a stereo amplifier.
