For the last month or so sold emails for auctions to domestic UK customers are coming through with the international postage charge shown instead of the domestic one.

So if the item ends at say £5 with free UK postage, to a UK buyer.  The email comes through as £5+£10 postage (my international rate).

Now the problem is the buyers email saying they've won the auction is presumably also the same, as I've received a number of irate messages from buyers who are receiving these emails and think I'm adding a rip off postage charge on that wasn't displayed before.

Once the buyer goes to pay, the postage corrects itself to free, so its just an error on the emails being sent out.

Its frustrating as its annoying customers and its resulting in an increase in the number of unpaid items. 

This is happening on 100% of the items, so for an example just look at any item Ive sold in the last month
