In item worth $199 is going to attract a fair amount of Customs fees, so it's entirely possible that your buyer has rejected the item.

For the future - anyting to Canada over about $25.00 attracts duties. Other countries with very low thresholds include the UK.

Whilst it is the the buyers responsibility to pay these, I have educated myself on which countries are a problem and I always advise the buyer upfront that they will incur charges.

Some items do take a long time to get to their destination - I had something from Israel which took 5 weeks to get here and there were no customs to contend with!

Lastly, even though postage was expensive, for that price I would have sent it tracked and adjusted the postage upfront before anybody purchased. Tracking is there for YOUR protection, not the buyers.

Unfortunate;y without tracking your only option is to refund. 😞
