Withdrawal from a purchase contract concluded in a classic brick-and-mortar shop within the period of 14 days is possible only in cases where the entrepreneur offers this to the buyer as a premium service. The law does not impose an obligation on the seller to grant the buyer the right to withdraw from the purchase contract within a period of 14 days even in case of sale in a brick-and-mortar shop. It is mainly based on the fact that the consumer has the opportunity to study, try and get acquainted with the goods in the brick-and-mortar shop, which is not possible in the case of sales on the Internet or, for example, by telephone. The period of 14 days is a time limit for familiarizing with the product and trying its functions. However, it should be borne in mind that familiarizing in this case means to such an extent that you would be able to familiarize with it in a brick-and-mortar shop.
If the seller does offer the right to withdraw from the contract in the brick-and-mortar shop, they may set their own terms and conditions for the consumer to exercise such a right. For example, the seller may require an original proof of purchase, original product tags, original box, etc. If you do not meet the conditions, it is at the will of the seller whether or not to allow you to withdraw, but you cannot force him to do so.
