Trying out a laptop in the store will give you an idea on how it works, what it looks like, and a good first impression to help you decide whether or not to buy it.  When you take it home it may be another story...

That is why you need to check out the return policy on your notebook purchase.

Different stores have different return policies.  Some only allow you to return the laptop within ten to fourteen days if it is unopened.  Others let you have thirty days to try it out, and if you don't like it, even if you used it, you can bring it back.  I also know of one store that lets you have six months to figure out if there are any problems with it or if you don't like it, and returning it is hassle free.

Be sure to ask about the return policy, and how it works.  Do they just take your word that it is broken, or do they require that they test it?  If they do test it, how long does that take?  Ask a lot of questions.  Below is a quick list of what you should ask about:

1. What is the return policy on a laptop or notebook?
2. How many days do I have to try it out?
3. Do I need a reason to return it, or can it be just because I don't like it?
4. Can I return it even if it has been opened and used?
5. Do you need to check it before I can get my money back?  How long does that take?
6. If I have XX (substitute the number of days in their return policy) days, does that count days you are not open?
7. What if the price goes down during the time I am allowed to return it.  Do you offer any kind of price protection? 
8. Can I have a copy of your return policy in writing?

This is just a sample list of questions.  I would suggest asking more than one salesperson these questions to ensure that you are getting consistent answers.  Talk to your friends that have used the store as well to get their feedback on their return policy.  If for any reason you feel that their return policy doesn't sound so good, don't buy there.  Sometimes it is also worth paying a little more at a different store to get a more favorable return policy.  Just be comfortable with your decision before you buy.
