We have a website in Opencart 220.127.116.11 on which we need to override currency conversion rates only for 8 products with fixed values.
We created a separate table for the same purpose with product_id, model, usd, cad and eur value rows that have those fixed values.
What would be the best way to implement the logic for: product price display, conversion, checkout, order placement all following this rule.
Please let me know if you need further details. Thanks.
