PURCHASING BOOKS/(OTHER ITEMS) FROM COROLLARY THEOREMS

1. THE PLACE TO BUY OUR BOOKS

Unless otherwise noted, you can purchase our books from our site only, using the instructions presented on this page. Note that we sell both physical and digital books, though they are processed differently, as it is explained further.

support@corollarytheorems.com or editcc@yahoo.com or cus@2graph.com

Include in your email to us the following mandatory data.

A. The ordering code(s) of the book(s) you want to buy.
B. The number of books you want to buy.
C. Your physical mail/postal address—be accurate and detailed in your address, then check it carefully for mistakes. Also, please include a local phone number (mobile, if possible), so that delivery people may contact you.

We shall respond to your email within 24 hrs with our price-offer, by means of an email from PayPal asking you to pay the Invoice amount. Note that our price-offer is valid for 3 days only; therefore, any payment received after the validity period may be automatically sent back to your Credit Card.

Please let us know when you make your payment to us (send us an email), so that we may start processing your order as soon as possible. All shipments are "economical", via "Air Mail", and they do have a tracking number.

3. PURCHASING DOWNLOADABLE BOOKS/TUTORIALS/KITS

In order to buy a certain downloadable item/book from us, you need to write an email to us using one (or two) of the following email address [we cannot guarantee which is the best email address since each has failed us at some point in time]:

support@corollarytheorems.com or editcc@yahoo.com or noi@editcc.com or cus@2graph.com

Include in your email to us the following mandatory data.

A. the ordering codes of the books/items you want to buy.

We shall respond to your email within 24 hrs with our price-offer, by means of an email from PayPal asking you to pay the required Invoice amount. Note that our price-offer is valid for 3 days only; therefore, any payment received after the validity period may be automatically sent back to your Credit/Bank Card.

Please let us know when you make your payment to us, so that we may start processing your order as soon as possible. Commonly, we send the download instructions within the subsequent 24 hrs.

ATTENTION
Downloadable books are commercialized as "software". This means, once we send to you the download codes, refunding is no longer possible. [This is similar to opening a CD package.]
