How much is my laptop worth?

I'm sorry it didn't post correctly here's what the post was supposed to be :
How much is my laptop worth? I got it last year (2013) in April, and this year I'm wanting to sell it and use the money to buy a better one. I was going to use it for some light gaming, but I want a better one because I'm planning on getting GTA V when it comes out for PC. It is a Dell Inspiron 15 (3521) here are the specs:
15.6" LED screen
4 GB RAM
Intel Pentium Dual Core (2nd Generation)
Intel HD Graphics
500 GB HDD
Windows 8 64-bit
It is fully functional, but there are a few slight, barely-noticeable, minor scratches on the screen and casing. So how much do you think BestBuy would give me for it?
 
don't bring it to best buy! The'll just jip ya'!

Sell it on ebay or something...being a newer laptop, you should get around $275 for it...

Heck, you could sell it on craigslist or in your local newspaper for more than bestbuy would ever pay.
