For paint and carpet both, go to Sherwin-Williams and ask to have a PC (professional coatings) sales rep contact you. The reps have a lot more price flexibility than the store managers, and they will battle for every sales dollar (I used to be a SW rep). Not all reps deal with carpet, but for an few thousand dollars or more a year (many investors will spend 60K+) they will find what you need. Pretty much any price quote you can get from anywhere (excluding remnants) Sherwin can beat soundly. They are a national account with all the major carpet co.'s - shaw, alladin, etc. The one area they can't always win on is installation, but they should be competitive. If you know an installer and are just buying carpet, no one will beat them. Good luck.
