Retail Merchant JNL is strictly for making prices. The 0-9 keys have large numbers, the shift position of the same keys have smaller, centered numbers, and the alphabet keys have a variety of smaller numbers with underscores in single digits, pairs of numerals and even a few complete prices such as "$1.00". Thrown in for good measure are companion words... "at", "for, "each", "lb." and "dozen"...
