I remembered: we bought a ceramic tile for the country in the spring at 2.5k / m2. In 2 weeks we go to the store, I see this tile already at 1.5k / m2. It is unfortunate, softly speaking.
Carrying back from the farm to the store a couple hundred kilos I did not smile at all. So I am:
1. bought this tile again;
2. took everything on the cart from the warehouse of issue - immediately to the department of return of goods;
Three I paid back on the first check.
The result: almost 23k savings
