X-feepro is an Order Total module that works on the Order total section only. It does not modify product price in any ways. It simply gives option of offering discount Or charging sub-charge/fee base on other Order Total parameter like Sub-Total, Total, Shipping etc. It is completely liked with checkout process.
On the contrary, X-Discount is a generic Module that works on product price directly. It simply works as same as how opencart special price and discount works. It modifies product price before showing to customers depending on the discount setting. It does not have any relation with checkout process.
------ Q. Does this module remove or interfere product's default special prices?
A. X-Discount is a totally independent module even it does not use database table of Opencart default special prices. It generates special prices on the fly and use cache for optimisation. Therefore, it will not remove anything, instead it will supersede the default features for products those are valid for discount and for other products default special price will work as usual.
Q. Can I disable default special prices/discount for all products If I want ?
A. Yes, you can.
Q. Does ribbon and countdown work with any theme ?
A. Yes but you must define css selector according your theme. You can request support if you need help.
Q. Can I define discount Or Special Price
A. Both. Discount can be set based on Quantity, Product Price and Special Price can be flat or percentage.
