I live in Ontario - Canada (20 min from Ogdensburg, NY Walmart store) - the system will not let me use the store's address for my Walmart online order? I get the message Walmart stores cannot be used for delivery? I had to use the UPS add $20. :-(

If you make online purchases at Walmart.com, you can have it shipped to the Walmart in Ogdensburg for pickup. Free of charge. I have done this many times. I also live in Ontario.

I've made an order from there before, I've had to use myusaddress.ca and pick up at the facility in Ogdensburg, for an extra fee, they will push your shipment to your Canadian address for you

I'm sorry, I've never had to deal with that before. Maybe call the store? See if they can help you?
