The sale is going well but the service is a disaster.
The cashier counts you twice the same article and when you come back 1 hour later to get a refund you are told that I'm lying.
In addition you buy an item in the store at a higher price than the website but there is no way to make you pay the difference with a prison door welcome.
Do not go there!
