Requirements

• max. 2 items of each product
  • [motivation] otherwise you're not individual customer but wholesale customer and you should go through different process
• *order value not greater than 20000 PLN for cash payment
  • [motivation] this rule is enforced by Polish law that requires cashless payment for B2C transactions above this value
    • [similiar case] there is also 15000 PLN cash payment limit for B2B transactions that we can include here too or leave it as separate feature
• products with limited availability have limit 1 per customer per quarter
  • [motivation] to avoid "scalping" practice by resellers, that purchase products like Sony PlayStation 5 console or NVIDIA RTX graphic cards and then resell them for much higher price (goal: fair chances for each customer)
