per questions before moving from osCommerce version 4 to Zen Cart

Hi,

I'm thinking very hard to give up on getting a osCommerce version 4 store set up.
And would like to know the best versions of Zen Cart addons that would best help to achieve the following:

1. advance gift voucher and coupon system,
2. points and rewards system - x points for every x£ spent, convert points to store credit/voucher/coupon once point equal x point, point for action,
3. advance sales manager - setup the next year's sales by categories, customer groupe,
4. price by groupe,
5. product price markup from supplier cost price,
6. multi shipping type in cart,
7. shipping type set by product - i have some product that can only be collected in store/location (as courier deemed them "dangerous or hazardous goods" like kitchen knife, DIY putty knife and some liquids),
8. Bazaarvoice,
9. Mobile Detect,
10. bundle products, cross seller, upseller
11. master product - will need to be assigned to the child product; this is so when the child product is sold on the site, the stock is deducted from the master product,

Any help would be helpful.

I'm happy to do some coding to achieve some of the above.
