Office Depot Price is not guarantee at Office Depot Internet

 I bought a desk at Office Depot and it is still in the boxes when I see in less than a week an Office Depot ad showing the desk discounted $170. Email Customer Services and asked if I can get the discount since usually major companies provide a price guarantee for 30 days. They said that the discount it provided just atb the stores. I contacted the stores and they said that this is only a delivery item. That I have to order it online. My only choice is return the desk and order it again and paying for shipping again. So Terry from Office Depot E-Commerce Support blatantly lied about that I could only get the discount at the store, since they do not carry the item.
