PURCHASING BOOKS/(PLUS OTHER ITEMS) FROM US

In order to buy a certain physical 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 cus@2graph.com

Green leaf 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.

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.]
