Modern sofas

Last September, our place was badly hit by a storm and some of our furnitures were disposed after because it was badly damaged. The water was almost knee deep and it was so hard to transfer out staff since it was just my sister and the helper with two kids. Now, its time to change a new sofa for us so I am looking for reasonably priced modern sofas for the living room. I only have a working budget and hopefully I wont go beyond that. I know that there's a lot of sale now in stores so i better check it out . Or i can also try online right? Lets see if they will deliver for free.
