That's been covered earlier: because it prolongs the scam. These guys did a good job of being thieves. If an item shows shipped, it satisfies eBay and PP and makes the transaction look legit, as if it's normally progressing, buying the seller more time. It's all about making eBay think you're doing what you're supposed to do.
Yes I understand that. But all you need is an envelope and a label. Why waste time folding up paper? Just ship good ol Canadian air.
