Overcharging glitch ( Postage set for £5, buyer charged £6)

[varia_art]

Hi,

I've set postage for £5 , and it was the only available option.
I've checked it a few times before and after the transaction.

On the invoice it says the customer was charged £6 for postage, what has been confirmed by the buyer.

Does anyone had a similar glitch issue?

It's another glitch. That postage 2.99 had been removed before the transaction because the customer couldn't see the second postage option.
