NEW matress, box spring and frame *MUST GO ASAP in Barrie, Ontario

Hello,
I have a great deal on a completely new pillow-top twin matress, box spring and frame..
I purchased these for my daughter, just over two weeks ago for xmas, shes moving back in, and when she saw it on xmas day we realized that it was the wrong size. Its only been unwrapped, set up and looked at by her, never slept on, shes too big for it and wants something firmer,.. but since its been two weeks, the store will not take it back. Im looking to sell this so i can reimburse at least some of what ive spent so i can get her the proper size and firmness. There is absolutely nothing wrong with the products, the matress is very very comfortable, just not right for her.

I spent 500 on the matress, 200 on the box spring and 70 on the frame.
Im only asking 300 for the matress, 100 for the box spring and 50 for the frame. 400 all together.
Please let me know if youd like to see it..
Thanks, shelagh
