These are Author's Editions, with material added to the original works, both of which have been out of print for a very long time.
IMPORTANT. When you click the BUY button you go to the page at Lulu.com where you can buy the book selected. If you live outside of the UK or US (where their main printers are) only use their economy mail. Similarly, if you live in the UK or US stick with the flat rate mail service. To make savings on postage I can only say buy more than one book, as it works out well that way. An easy way to buy various books is to use www.lulu.com/spotlight/mickmercer as the main guide and backspace to it regularly.
