my shop is set up as a showcase with prices...

we get customers to join our site and we reward them with a $30 discount..

when they log in at a future date they see all prices less tax...

i have the shop set up to

Display Prices with Tax true Info
Display Prices with Tax in Admin true Info
Basis of Product Tax Store Info
Basis of Shipping Tax Store Info

this is creating unhappy customer when they come to purchse

i want them to see all prices with tax inclusive whether they are logged in or not
