Legal analysis: if there is no online sign in the store, it can be regarded that the two sides have not reached an agreement on the store transaction, and the buyer and the seller can cancel the transaction before signing the contract. Buyers who have acquired the store should return the store after canceling the transaction and pay the appropriate store occupation fee. A reliable electronic signature has the same legal effect as a handwritten signature or seal.

Legal basis: Article 13 of the Electronic Signature Law of People's Republic of China (PRC) shall be regarded as a reliable electronic signature if the electronic signature meets the following conditions at the same time: (1) When the electronic signature production data is used for electronic signature, it belongs exclusively to the electronic signatory; (2) When signing, the electronic signature production data is only controlled by the electronic signer; (3) Any changes to the electronic signature after signature can be found; (4) Any changes to the content and form of the data message after signature can be found. The parties can also choose to use electronic signatures that meet their agreed reliable conditions.
