I bring to your attention New Year and Christmas gifts - these are virtual cards of my website worth 20, 35 and 50 euros. Electronic cards, their delivery cost is "0". You can give them to your colleagues, friends and loved ones in the most remote corners of the world. You can use them to buy any books or magazines on this site, pay for delivery or pay for any of my seminars. The validity period of the cards is not limited - they can be used on this site at any time during its existence.
The card purchase offer is valid until January 14, 2024. I'm sorry, but the offer is not possible on the territory of the Russian Federation.
