Pricing Rules
Buy prices are flat per kg — one price, all grades. Grade is recorded at intake for shelf placement only, not for payment.
Sell prices are graded — G5 commands the highest price, G1 the lowest. Cash and credit variants on both sides.
Buy — 1 price per kg · all grades
Sell — 5 prices per product · G1–G5
Credit = cash + 15%
Bulk barter — Aidan only
