You can use the Product Search function of Google and search for Wireless ergonomic keyboard and mouse combo. This is the best way to find this product on the Internet. Also you can enter Amazon.com or overstock.com and search for electronic products of this kind, but I am not sure that you will see all the available options. Just think that if you enter Google and search for Wireless economic keyboard and mouse combo, you will see almost any site in this world that contains this product or information about Wireless keyboards and mice.

One of the first results that appeared in my list was the Pixxo 2.4 GHz Wireless ergonomic keyboard and optical mouse, that has 1600 CPI. What can we say about the keyboard? This is a complex keyboard, that has 13 Internet or media hot keys and one volume wheel. This means that you can simply press one of the keys presented on the keyboard and go directly to the location where you want on the Internet. The reliability of the keyboard is from 5 to 10000000 presses. It is a bit large (this interval from 5000000 to 10000000), and at the same time you cannot count how many times you press one of the buttons on the keyboard. I wonder how they do the tests to see how the keyboard resists to 10 million touches in the life of the keyboard. Anyway, the keyboard and the mouse as well have an economic design, which is created to prevent the arms and the fingers from getting fatigue. 

The keyboard can work using its batteries as well, situation that is not necessarily encountered when it comes to keyboards. We know that we attach the keyboard to the computer or we plug the keyboard directly into a wall power source in order to use it, but we don't know that you can use two AA batteries in order to allow the keyboard to function. Well with this Pixxo Wireless keyboard and mouse, you can do this exact thing. The price of this item is of $20 and it can be bought online.
