Do I need mods for the following?

Hi New to ZenCart, and as I cant find a demo to see the store in action Im having to install it to see what its like.

Does the following functions come straight from the box or do I require mods? If I need mods could you point me to the right direction.

1. WorldPay merchant payment
2. Debit Cards for the UK
3. Mailing List

If you can help that would be appriated.

here is a demo site... it isn't the newest version but it works http://www.opensourcecms.com/index.php?option=com_content&task=view&id=300&Itemid=0

Here is what I know about your queries:

1. WorldPay merchant payment
   There is/was a port of this module. You should pm networkdad for details & if it still works for 1.3.x

2. Debit Cards for the UK
   I have not seen a module for any debit cards UK or otherwise

3. Mailing List
   Mailing to either a specific customer or all customers is an included feature of ZenCart. There were/are also mods for individuals that are not customers with accounts to receive newsletters and could be adjusted so you could add additional recipients to your mailing lists.
