I have items set at £2.50. Vat is included in the price.
When I place an order for 1 item via the front end the vat is calculated at £0.42 and the total comes to £2.50. This is correct. If I then make that 2 of the same item the vat goes up to £0.83 and the total to £5.00. This is also correct.
However, if I place an order through the admin panel, for 1 item the totals are the same but if I make it 2 of the same item, the vat comes to £0.83 but the total only goes up to £4.99.
Has anyone else experienced this issue? Is there a workaround?
