I completely replaced all my wall to wall carpets. Home Depot had a great promotion with free underpad and great price. You can also pay it in 6 months with their credit card.
The price is great on a couple of styes/colours in stock.
They came and measured my place and the cost for it is applied to my order.
The installation is outsourced. The installer was late and his assistant was sick. I had to help him with the carpet. When he put down part of the carpet he noticed the pattern did not match. He brought back carpet and I had to deal with store. After a while, I was able to get a better carpet without pattern for the same price. Had to live on concrete floors until new carpet was installed. Store called later and wanted me to pay higher price. After some time agreed to not charge extra due to problems. Carpet is well installed and good quality. Hassle in getting carpet installed was big problem but no one had a better price. Had to call them once to stretch carpet but they did it without cost.
