some ideas bellow thank you!!!

1. Option to show price without TAX and add TAX just in final bill this is more usable in Canada.

2. Options to give discount to all products at same time.

3. Show MSRP price and discount price on shopping card together.

4. Add compare function when customer can see 5 products on same page and compare it.

5. Add option for customer to send an offer if product mark as “open for offer”

6. Option to see all products in one table and possible to change if from one place but not open product one by one

. Make shipping price more flexible, today we can use weight or fixed price, good to have option to use zip code too for each product or country names.
