I live this calculator. Very easy to calculate margins on the fly and not too busy with too many functions. I really like the larger keypad, solar is nice so I don't have to worry about batteries and it is very easy to use. Great for a rep who is working up margin or mark up.

LOVE the Victor calculator. No other brand can compare and hold up to heavy, everyday use. Keys are big enough to avoid "fat-fingering". Got the best price, quick turnaround (ONE day!!) and excellent customer service!!

We love this calculator. The keys are big and the display is big. If you want a nice big calculator, this one is great.

Latest Question and Answers

Hello, I am interested in knowing how a paperless calculator prints?
asked by Jae on December 19, 2017

The calculator does not actually print, you are able to view the entries on the screen. You are able to scroll up and down to see up to 300 Entries (Instead of looking at paper)! This calculator also has a Check and Correct feature which allows entries to be modified on the screen.

Can I order just one of the National School Calendars?
asked by Linda Bruckner on June 14, 2016

Unfortunately, no. Riegle Press National School Calendars are only available in quantities of two or more. Many of our customers team up with a fellow teacher to meet the minimum order requirement.

Additionally, we do offer a number of other academic planners and teacher planners that don't have minimum order requirements and can be purchased individually. Two of the more popular alternatives are the Blueline® NotePro Undated Daily Planner and the Ward® Lesson Plan BookWe get excellent customer feedback about both.
