Not in all cases. All calculators are tested upon arrival to finalize the buyback total. If it is concluded by our specialists that the calculator received does not match the provided description, then an adjustment will be applied to your payment for the correct total corresponding with the suitable condition. If the calculator is damaged to the point that it is not saleable then we will recycle the unit and no payment will be sent.

We are very lenient when it comes to our gradings and make every effort to clean/refurbish calculators that we receive. Very rarely will we lower the specified grading from what was submitted in the buyback forms, but this does happen. The final grading our your calculator should reflect the ‘new’ and ‘used’ definitions, as specified here. Please see our terms for bulk buybacks here.

If you have any concerns about a pricing adjustment please contact our customer service via email ( or via phone (609-666-CALC).
