I'm located in canada, and i buy from the US quite often. I've found that when my orders come in via GSP (or whatever it is, just gonna call it GSP for simplicity), the shipping takes twice as long than it would if it were shipped direct via USPS > Canada Post.
Also, I've had them lose a few of my items in the past
Is there a way that I can blanket opt-out of having my orders shipped through GSP, seeing as they make the delivery take longer, and lose my stuff sometimes?
Or is it more of a message the seller and ask them not to use GSP to ship out.
