How do I handle cross-border DTC from Canada to the US?

Cross-border DTC from a Canadian store to US customers has three big cost levers:

• Shipping — ChitChats / Stallion / Stamps.com let you "relay" parcels to a US drop-off point, then ship via USPS at domestic rates — often 50–70% cheaper than UPS / FedEx cross-border
• Duties & taxes — under USMCA, Canadian-made goods under USD $800 (de minimis) clear duty-free into the US. Use Zonos or Easyship for landed-cost calc at checkout so customers see the all-in price
• Currency — offer a USD checkout for US customers via Stripe’s multi-currency, or wire a separate USD store view with a USD price book

For Magento we configure: (a) ShipperHQ to route US orders through ChitChats/Stallion, (b) Zonos extension for landed cost, (c) Stripe multi-currency or a USD store view, (d) duty-paid (DDP) vs duty-unpaid (DDU) toggle in the checkout.
