I´m just about to launch a webshop for a customer and when I´m testing to order, the price for one of the products (not the other) changes after the order has been sent.
The price for the product is 125 SEK. If I rise the price above 500 e.g. 510, the problem disappears. But I have other products below 500 functioning without problems. The "125" product is the latest added.
The fields for product price and cart subtotal changes from 125 to 26. In the back end, in the Order Details (Edit Order) the product price is set to 1 and the VAT is correctly 25 (1+25=26).
The grand total appears to be correct.
I have checked and compared all settings for the new "125" product and the rest. There is no difference. I have also tried to add another product, and the same problem appears there (as long as the price is below 501).
