Please be aware that we ship from Russia. I post the books as soon as I can, but if you are ordering from abroad, delivery could take anywhere between two weeks and three months. I obviously hope your orders arrive as quickly as possible, but this depends on the postal service. Thank you. Currently because of the pandemic, we can't ship to South America. We hope that borders will be open again soon, and we will be able to ship the books to our dear clients who are still waiting.
