Prior to returning any merchandise (defective or otherwise), customers must contact Cartridge Warehouses Customer Service to obtain a Return Authorization(RA) number and shipping instructions. All non-defective returns must be in resalable condition and in the original packaging. Please do not mark, or write address or Return Authorization Number on the outside of the original packaging. A 15% restocking fee will apply for all non-defective returns. Returns are only accepted within 30 days of the original invoice date. Return Authorization(RA) numbers are valid for 15 days from date of issue. All returns are subject to inspection by Cartridge Warehouses on the resell condition, and credit will be issued after the product has been received and inspected. All return freight shipping charges will be the responsibility of the customer, unless the error was due to Cartridge Warehouses. All sales made on special order, non-stock items, closeout or discontinued items are final and are not returnable.
