Is it permissible to take products from a store without paying for them to compensate for a price difference that was previously paid?

Selling merchandise at a price higher than the market rate is not injustice, and the buyer has the right to bargain. What the questioner resorted to is forbidden in Islamic law, and he must repent from it by ceasing the act, regretting it, and resolving not to return to it. He must also guarantee what he took by returning it to the store if it is still there, or returning its equivalent or its value. The right must reach its owners by any means. It is also possible to seek forgiveness from those in charge of the store without revealing one's identity.
