Coupons and the charges module in version 4

1. One requirement I had is to be able to add discount vouchers to the cart. I see that the previous version of e-commerce had a coupons module. Is this module on it's way for version 4? Is there a workaround that I can use to make simple voucher codes. Maybe using the charges module?

The coupons module is a single use discount code. If you want simple use codes them you will need to wait for this to be upgraded. But basically what I am going to do it set it up as changes filter and calculation which will check a form field for the code, and see if they are valid and apply the discount.

However if you want to use a multiple use discount code, then there is an enhancement that I am going to be doing in the next few weeks to charge to be able to add a form field to the checkout which will the customer will be able to add the discount code to and then you can set up a charge to add a discount based upon a discount code. This field will also be able to be used by multiple charges so you will only need a simple discount code field on the checkout.

2. I'm will not be the maintainer of the site once developed. The client wants to be able to discount individual products. I think the easiest way for them to do that would be to be able to set a discount when editing the actual product. The charges module is probably a bit complicated for a non drupal person. How would this be done making use of the charges module?

Most likely the easiest method is to add create a charge which filters based upon a taxonomy term apply discount this when a term is present.
