So here a question for you guys
I have been shipping my parts via canadapost which once it crosses the border USPS takes over.
Should i change my shipping method ?
Is USPS getting bad to ship with?
Someone said you cant track it that well on USPS when i log on i can see where it roughly is .
Sorry just want to make sure my products make it to you guys and you are all happy.
