Need New Mouse For My Lap Top

Yesterday my mouse is acting weird on my lap top. I cannot click anything in the monitor. I do not use the mouse on the lap top. I like the regular mouse. It is easy to use than the lap top mouse. I know I am not savvy in gadgets. I will search online or perhaps go to Walmart. I hope they are not expensive. If they are, I have no choice but to buy durable ones. I cannot live without regular mouse. It is very important with my blogging. Do you recommend any type of mouse?
