quick question. i've never used shipping labels before. i've printed off my label, and it will be shipped internationally. do i have to have my signature on the label? i tried looking into it via google, but the answers i found were kind of unclear, but from what it looked like, some people had there package sent back if it wasn't signed? also any other tips on labels would be nice. i was kind of confused and i'm hoping it'll send off fine haha, especially since it's making the journey from canada to asia. i just used the paypal labels for this one, i'm not sure if different services are better or worse, so if there's any suggestions where i can get labels printed for the future i'll be happy to hear!
