Add to cart. Pre-order in our group buy. Pay off-site.
This shop works like a normal cart — browse, add items, and submit. Your order becomes a pre-order in our current group-buy batch, not in-stock retail. Prices are shown in USD; we don't take payment on this site. When it's time to pay, the CAD amount you send follows the PayPal exchange rate that day, and we'll reach out to arrange it.
