It depends on what you’re buying. For me.it’s not as much about the review its more about the product info.and price. For books or eletronics online is better because you don’t need to see the product as much as you need technical.information.
For Clothes, perfume, fresh food etc I prefer to go to a store since it’s important to see it. Clothes are always a problem when they don’t fit and if I’m goingo to have to return it (if it doesn’t fit) it’s just faster to go to a store.
Sometimes prices are a thing too, it can be a lot cheaper online and unless you’re rich this does make a difference
