If you shop online, ask the seller questions about the products, request additional non-generic images, and confirm that they offer after-sales service. You can also find out if the listed phone number and email address do not exist or are fake.
Contact an authorized reseller or official brand representative to check if they know the seller or suspicious online retail location. Keep in mind that some luxury brands cannot be sold online, but only in physical stores through the official retail network.
