Есть ли российские платёжные системы в коробке, и если нет, планируются ли их реализация?
Yes it's interesting.
How can I contact to you?
We are about to release integration with Russian payment system in couple weeks. Please contact me directly if interesting.
We currently don't have any Russian payment gateways. We do have implementations however done as part of the http://kitmall.ru/. We'll consider including them as part of the product.
