Being that I live in Canada is there much savings going through a group by rather than direct?
From what I can gather, direct shipping from China to Canada is somewhat more expensive than what they charge for shipping to the US (order volume may also have some impact on that as well).
However if you end up going through a group buy as mentioned above, you will have to pay for the shipping to the US (usually included in the group buy vendor's quote), then additional shipping to Canada (not cheap). If you live near the border, you can use a mail drop service and carry them across to reduce this cost, BUT...
Currently you will likely have to pay an additional 25% tariff at the Canadian border on almost any goods coming from the US (even if the country of origin is China). In addition you may end up having to pay the Group Buy vendor for any additional US tariffs, depending on what happens in the next week or so. Shipping directly to Canada will likely avoid most of these costs.
Regardless of which way you go (other than using the US mail service and carrying them across yourself), you may end up facing a Brokerage Fee from the courier or postal service, often in the $20-$90 range. USPS/Canada Post fees are usually cheaper, Fedex/UPS fees can be pretty steep.
And of course GST/HST and/or PST will be collected at the border as well, regardless of which method you end up choosing.
Buying directly MAY end up costing more than, less than, or the same as doing the group buy from the site vendor. You would have to contact Broken Arrow and
Tina separately, find out ALL of the expected costs, and do the math to see which is the best option for you.
One additional note - whoever you end up purchasing from, MAKE SURE that they fill out and attach the required Customs Declaration (including country of origin, contents, value, etc). Incomplete or missing documentation can (and most likely will) cause your shipment to be refused, ignored, lost or indefinitely delayed. Often times the shipper will refuse to provide refunds if the shipment doesn't arrive, even if they are the reason it gets stuck at Customs.
