Shipping rate changing in cart

In testing a product, we’ve set a £30 shipping cost when the cart total is over a certain amount.

At checkout, the price briefly shows at £30 before inexplicably changing to £25. There’s no discount applied.

The product in question has a 20% tax (not applied to shipping). However I calculate it, the total seems to be incorrect or off by £5.

What might cause the shipping rate to change in the cart?

Hey davesmyth,

I have the same problem. As it feels for me the currency gets converted from your currency to USD. I guess thats a deeper issue or maybe a bug in a certain way.

Best regards
