If you're looking for something to buy for your house, then how about dressing up your entertainment room a bit? You could buy a new flat screen TV that will surely make your watching experience even better! While you're at it, buy some home flat mounts for it too!
Of course, you can buy furniture too! Maybe get a new couch or carpet? It depends on what you think will make your place more enjoyable and comfortable to stay in. You don't have to splurge to get that much needed change in your place! As long as you like how it's gonna turn out, then that's okay. :)
