I bought a laptop here, but on the day of delivery a message comes that they were mistaken and the price is already different. No discounts were offered, categorically or refund or pay extra or we will bring another configuration (another processor). The position of the seller - we act in accordance with the offer agreement, which is controversial, but it's not to go to court because of such pettiness. In general, keep in mind that according to the concept of the seller and "according to the contract", the store changes the cost of the goods already paid for at any time convenient for them.
