Thanks Pam, Valerie, Sue, Dave, and Robin for your responses! This is a learning experience for me. After contacting the seller about the possibility of loss as her tracking number said that it was delivered, she said that a person had received the package in Lewiston NY. Well, I am not anywhere in NY! Perhaps Sue is right. Maybe my package somehow is being held up in NY. But it can also possibly be misdelivered to a wrong address as Dave pointed out. Anyway, I hope it is the former case as there is still a chance that I can get my seeds. If misdelivered and the package got thrown out by the wrong recipient, the seeds will be lost for good.
Sue, as a buyer of the seeds, I am not sure I need to do anything extra in terms of paperwork to purchase seeds from Canada. The seller did not specify anything on her sales page on the LA either. I had bought from her before and from Emery who is also in Canada. I had received seeds from Emery from Canada in February with no issue. The seller did say that she did acquire a phytosanitary certificate for the batch of seeds that she sent with my seeds shipment.
I am going to my post office tomorrow to find out if they can give me some information about this package with a Canadian tracking number. Hoping for a happy ending!
Robin, so glad that you were able to work things out with your seller. I hope my seller can do the same should the package ends up in twilight zone.
