changing shipping and payment based on customer

Hi,

I have a cart that is using the Dual Pricing - Wholesale Pricing add-on.

I would like to be able to change the payment and shipping options that show based on there pricing level with in Dual Pricing Add-on.

For example, I am using the firstdata payment module, and when a retail customer shops, I want them to be charged for the merchandise and use the table shipping that I have set up.

When a wholesale customer shops, I would like to use the first data payment module, but set it for processing the credit cards offline and not charge them shipping, but I will add it later when I process the card offline.

Is there a way to make that happen.

Any help would be greatly appreciated.

In a physical retail environment there are usually a lot of parameters that define a wholesale and retail customer. EG: here in the UK we are obliged to show Vat Inclusive prices for consumers, and B2B customers like to see vat exclusive. That in addition to a range of other differences

So we generally build 2 separate sites. One for B2C and one for B2B

See: http://coffeelogic.co.uk (B2C)
And: http://logicvending.co.uk (B2B)

we find this a lot easier than trying to code difficult behaviour for the different customer sets in a single site, and then manage the practicalities of logistics and fulfilment.
