The internet is open 24 hours a day 7 days a week. You can find the things you are looking much faster when you enter an online store. Simply put the item you are looking for in the search box and it will guide you to what you need. Unlike most retail stores where the clerk has no idea what you are talking about. Online stores provide more information about the product you want to buy.
Most online stores offer customer reviews about the product.
The product selection the internet offers is much more extensive than any local retail store. If you want it you can bet you can find it somewhere on the internet. For example if you have ever wanted a Scottish kilt then you can find it online. Your credit card information is safer than when you use your card at your local retail store. The truth of the matter is that more fraud is credited to stolen paper receipts than computer hackers breaking into a site and stealing your individual credit card number.
