Soon, when you walk by a shelf filled with produce, it may have electronic labels, personalized advertisements, RFID (radio frequency identification reader) technology and IOT (internet of things) sensors. Smart shelves with digital displays are coming to more supermarkets as paper labels are replaced with advanced technology.

Buying books on the Internet is a great way to save time and money. Online bookstores offer new books and used books that can save you lots of money. They are far better compared to traditional bookstores as they offer much broader kinds of books. Another advantage of shopping online is that you can also read the book reviews as well as readers’ reviews to get an idea whether the book is worth buying. Online bookstores offer great discounts (折扣) to regular customers, which is a big attraction for book lovers.

For book lovers, the most important thing is to get books on time. Therefore, you need to find a reliable (可靠的) online bookstore that will be able to provide fast deliveries (送货).

Here are some tips to use when choosing an online bookstore. Some online bookstores are popular for fiction books; some are for non­fiction books or novels, etc. Understanding their specialization will help you get the right kind of books in time. Check whether you will be buying the books from a third­party seller or directly from the website. Although the website could be reputable (声誉好的), third­party sellers advertised on their site may not have a good reputation. Never jump at stores that offer super cheap prices, as books sold at such low prices could be in very bad condition.

Most of the popular online bookstores offer useful tools. One tool is a wish list tool on its website. You can update (更新) the list of books you wish to buy in the future. The bookstore will know what you want and will email you immediately when the book of your choice is available.
