This depends on the type of your order.

1. If you order something from stock, e.g. a limited edition t-shirt, you have a 14-day period during which you are free to return your order for a refund. It’s important to note, however, that this is a small business and I cannot offer free return shipping, so you will have to pay for the postage yourself and will be refunded only the order price, not the postage. 
2. If you order a product that is printed on-demand, returns cannot be accepted as the product was specifically printed for you. In the rare case that the product has some obvious defect, you will of course be offered an exchange/refund. Please get in touch through hello@goldmundsupply.co if this is the case.

To find out if your item belongs to (1) or (2), check the info in the product description. Moreover, I strongly recommend to double-check the size guide on each product page to avoid returns altogether.

If you have made a mistake and want to cancel your order, you can do so. Since most products are specifically printed for you once you order, however, please be aware that your cancellation has to made as soon as possible by sending an email to hello@goldmundsupply.co. The deadline for cancellation is 12 hours after order confirmation.
