Use coupons (check CC), makes everything so much cheaper. You only need the number at every KFC i've been to, either memorize it or write it down if you want to save time. The numbers are PLUXXXC or W, the are located in small writing at the bottom. Although it says limited to one coupon, KFC staff will generally let multiple, but don't overdo it, if you want more than two, just get the mate behind you to order, as long as it's a different customer.
