How these sources become product rules
The current configuration stores rates as decimal strings and identifies the correct monetary base for each fee. Standard US commission is 8% of the post-coupon item price; processing is 2.9% of the buyer-paid total plus $0.30 per transaction. The reduced Coins & Money profile and current Pallets promotion use 4% commission.
Qualifying high-value profiles cap the standard-rate commission base at $1,500 while processing still applies to the full buyer-paid total. Temporary and category-specific rules remain labeled as such.
Components are calculated with decimal arithmetic and rounded half up to two USD decimal places before displayed totals are assembled. Fee changes require a new reviewed rule version and automated examples.
The Weekly Orders Report documentation defines the canonical CSV field dictionary and known transaction types. Header aliases are matched without depending on column order; unrecognized fields and transaction types remain visible as schema warnings instead of being discarded.
