Purchase clocks with timer functions from retailers such as Amazon.com, Bed Bath & Beyond, Best Buy and Walmart, as of April 2015. Sites such as Online-Stopwatch.com also offer many different free timer and clock tools.
To locate a clock with timer capabilities on Amazon.com browse through the site's Kitchen and Home Goods categories to find the section dedicated exclusively to Timers. The items in this category all feature some kind of timing function, though not all have standard clock components. Users should look at the included product picture for a clock face to identify the items that offer both features, as well as check the descriptions of individual listings. If a user is unsure of the functions of an item, she should read through the user reviews and question and answer section for additional information.
Listings on Walmart.com also contain reviews and a question and answer section in addition to product pictures and descriptions. Users who purchase a timer clock on the site also have the option to pick up the device from a nearby Walmart store. This in-store pickup feature is also available to customers shopping on BestBuy.com and BedBathandBeyond.com. In all cases, the user pays for the product on the site and is then able to pick up the item after a specified amount of time.
