We were in the market for carpet for the main areas of our home. After shopping around, we found Carpet To Go to be 25% less expensive! That is a huge difference! However, there is a downside. Although we were told that the carpet was midgrade and of good quality, with a 10 year wearability, we later found out (AFTER installation) through some detective work that it was a lie. The carpet was low grade, poor quality, and only a 2-5 year wearability! There is nothing we can do now, as we DIDN'T GET IT IN WRITING! Lesson learned for next time.
If you want good prices, I'd say check them out - with a warning - do you rown research on the carpet you want first, and then whatever you are told by CTG, MAKE THEM PUT IT IN WRITING!!
