From an outside perspective, I am getting a different take on your situation.
You say that they did not cut corners and you received a great specimen and that they filled you order in a timely fashion.
Considering that they missed a deadline (2?) for delivering your item and only did so after a PayPal claim was initiated, calling that an "acceptable time frame" gives them undeserved props. If anything, the shipping agent is the reason for the quick delivery.
Considering the above and the fact that you received a choice specimen leads me to think that they had no need to cut corners because the knife was already done. They either expected to ship that to someone else or your PayPal claim lined up perfectly to the real delivery date they intended. Based on their history, I lean towards the former.
