Since there are usually fees charged to the merchant when you use a credit card (typically ~2.9%), merchants are usually reluctant to let you use them for big purchases. For example, about a year ago a tried to buy a $15,000 car on a credit card (2% cash back, yay!), however the dealer balked at paying $435 in credit card fees and limited the amount I could charge to $5000.
