There are "buy now" buttons against most items. Where there is not a button, please enquire via CONTACT. 

For digital items - there is not an instant download - the files will be sent as email attachments.

For printed items, the price includes postage within the UK. 
Outside UK - please enquire.

There is no "add to basket". If you wish to purchase several items you are welcome to order each in turn (each one takes only a few seconds if you are using PayPal) but if you would prefer the items on a single invoice, again use the contact page to ask for one to be sent.
