POST creates new resources or triggers actions; it is not idempotent.
Step 2: Analyze repeated POST effect
Sending the same POST twice creates two separate orders, causing duplicates.

Quick Check:
POST non-idempotent = duplicates possible [OK]

Quick Trick: POST repeats create duplicates; use PUT for idempotency [OK]
