nopCommerce changeset c35e35cdb984 (i.e. beta 2.0 with a few bug fixes)
No modifications
MS SQL 2008
Store set to use British Pounds as primate store currency, and primary exchange rate currency
EU VAT enabled, shop country set to be UK. No changes made to tax rates (i.e. they're all zero)
Placed an order for an item priced at £3.00 - the value shown on /orderdetails/x (where x is the order number) is £1.83
Value for order shown in admin is £3.00
Repeated for another item - similar result (item was £17.56, shown in order details as £10.71
Might be me doing something dumb, but the discrepancy between the admin site and the order details page makes me think it is probably a bug
Cheers
Tony
