Zen Developers - Surely this is easy?

The practical use is that, certainly in the UK, it is usual for the public to want to know the final price, and the "trades" want to see the pre-tax price.

Some time ago I wanted to create a tax free shopping module that uses the customer groups to allow customers (belonging to a "taxfree" group) to buy taxfree. I never really finished it but the basic idea does work, and I attached the files to this thread. Of course it is not exactly the same as what you asked for, but I think converting it to a taxfree button (i.s.o. a taxfree group) should not be difficult.

Paul, I have a client asking me for very much the same thing. He wants the store to show prices with tax for everyone except those put in the "reseller " group. I was surprised that I could not find such a module. Could you please post your files again?

What kind of issues did you come up against when trying to implement this module?

Thanks in advance!
