Exchanges and Returns: We are only able to accept returns for UNOPENED and UNUSED markers.

Credit or Exchange: Please email [email protected] with your Order / Invoice number, reason for return, and/or items you would like to exchange.

Credit will be issued or a replacement will be sent to you after we receive the unwanted markers back. To help speed up the process, please include a copy of your Sales Receipt or Invoice in the box with the markers. If a copy is not available, please include your name, contact email and phone number, and address to which the order was shipped.

Error with order: We try our best to be as accurate as possible when shipping your orders. Please let us know if there is an error as soon as possible. Email [email protected] with your Order / Invoice number to arrange for a replacement. You will be sent a return label to send back the items you received in error at no cost to you.

Fraud Protection:
Due to an increase in fraud attempts we reserve the right to cancel any order placed that does not meet our fraud protection rules. Please note orders over $50 are required to be shipped to the billing address on the order unless previously approved otherwise.

Sales Tax / Tax Exempt Orders: We currently collect tax on orders shipping to Tennessee, California, and North Carolina. If you are tax exempt and your checkout estimate shows sales tax, please first create a customer account on the website and then contact us prior to placing your order. We will need a copy of your tax exemption form emailed to [email protected]. You will only need to provide this once.

Quantity Pricing: Additional price discounts available for large quantity orders. Contact us for pricing.

Specials and Coupons: We occasionally offer specials and coupons for specific brands or products. These discounts can not be combined with any other discount, coupon code or corporate discount. If your order is submitted with the discount and you already receive a corporate discount the promo discount will be removed. We reserve the right to revoke promo discounts on orders that already have received a discount.
Marker Supply coupon codes are announced on our website, social media, and/or newsletters. Discount codes and offers found on third party coupon websites may not be legitimate.

Color Charts: We have done our best to represent the color of the marker's ink. Due to variations in monitors, the color may not be exactly as represented on your monitor. The effects of some colors, such as fluorescents and metallics, will pop more than the color charts can show.

MSDS Sheets available upon request.

Please call us at 866-354-9431 if you have any questions.
