We had 2 gift coupons for 5000 tenge.
We called one of the chain stores and were told that we could just come and pay for the product only with them.
When we arrived, the seller told us that we could use them to pay with money. When we chose the product, it turned out that only gold products and with natural stones (which is too expensive for us ~ 100,000 tenge). Wasted time and negative fallout.
Sellers are unpleasant.
