For those who travel further from Russia, for example to Almaty or Astana, I recommend changing back to back so that there is enough for the road, etc. The rest should be changed in large cities, since the exchange rate near the border may differ by 10 percent. This is especially true on weekends
On the way to the airport, I changed rubles to tenge. The exchange rate was slightly lower, but it was a day off and other exchangers were not working, so 5 stars for working on the weekend ✌️
