Looking for a new laptop

My sister's laptop finally gave up. It just won't open anymore, won't charge , there's nothing you can do anymore. It has been showing some signs of breakdown when the battery life got really short, and the screen would sometime flicker. So now she is looking for a new laptop because she needs it for her online job as well. She now looking for a new laptop, specifically acer laptops . I have an Acer before and I can attest to it's durability over time. I just gave it to my cousin who needs a laptop for college. We are still searching where to find the perfect selling price. Do you know where we can grab an acer laptop with a big discount? I hope we can buy soon because she has a lot of work lined up and she currently shares with my laptop to get some work done.
