Customer Service


We make every effort to absorb all shipping costs. Shipping in Canada is free, via Canada Post lettermail or expresspost (sometimes it makes more sense to ship express).

Standard shipping to USA is also via regular lettermail, which in our experience takes about a week to most areas in the lower 48 states. Contact us if you need something sooner.

International Orders

Currently our website only accepts orders shipping to Canada and the United States. Contact us if you're interested in one of our books - we can work something out.


Credit card payments are processed by Stripe. At no point does Dumagrad have any information about your credit card.

Contact us if you wish to pay via another method. We can arrange direct payments via Paypal, or even Interac Etransfers (for Canadian customers).
