Shipping and handling through affiliates, retailers listed on our page that are not a part of the STM-Store and TNC Network, will be handled through those individual affiliated retailers and not the STM-Store.
For U.S. customers, STM Store will provide return labels using UPS or USPS for secure shipping and return package tracking. Simply print your shipping label and place item(s) in original packaging. All you need to get started is your order number and zip code. Your order number can be found in your order confirmation email or on the packing slip next to ‘PO Number’. Please include a copy of your packing slip with your return, if possible.
Affiliates are individual retailers and service providers who advertise their goods and services on our site. They are not a part of STM-Store or TNC Network beyond advertising.
For purchases made through affiliates, all return and exchanges are made through those individual retailers and service providers. Check with those retailers/ service providers for their individual return exchange policies.
