Pay what you can/want. Seriously. Someone was very generous to me recently and I would like to pay it forward. Pay me what you can or want for the calculator. Check it out, decide what you can or want to pay, hand me the cash and I hand you the calculator. It's that simple.
Used in excellent condition. Let me know if you have any questions.
