In order to minimise costs and therefore our prices, we only accept payments through our website. So we do not take purchase orders or other types of payment. Also our prices do not include any form of reclaimable sales tax or VAT.
Although we use PayPal, you do not need a PayPal account to pay. PayPal are just our payment provider, so you can use a major credit card such as Visa or Mastercard. Payment is in your local currency and PayPal take care of any currency conversion using their exchange rate at the moment you pay. You can estimate the price in your own currency by using Google to calculate the current exchange rate and adding 4%. We only see the final amount in GB£ and so do not see any conversion charges that PayPal may make.
We know that many of our customers, especially government departments, cannot buy online and so many have to go via a reseller. Though for small payments your organisation may allow you to make a personal payment to be claimed back on expenses.
Note that we do not have any preferred resellers, and so cannot provide any contacts. But most are generally happy to help customers they regularly work with or would like to do business with. So you may wish to contact a reseller that you know of or already use. Note that they may wish to charge an admin fee in lieu of any discount from ourselves.
