Online-shopping.
Are there disadvantages? Unfortunately, yes. Let's look at a few:
You can't try things on. If you're buying a clothing item, you don't have the ability to feel the material, try it on, and see how it's made. Unless you know your measurements and are familiar with the brand of clothing offered, this could end up being a bad experience.
You can't get an immediate answer to your question: If you have a question about the item you're looking at, you probably will have to wait at least 24 hours to get a question answered (however, many sites have "instant chat" enabled that take care of this issue).
Privacy and security: Privacy and security are legitimate concerns for any online shopper, but there are precautions you can take to make sure your transaction is a safe one. For example, paying attention to HTTPS protocols, knowing how to identify online scams and hoaxes, surfing anonymously, and keeping your Web usage private.
