When I make an offer on an item (as a buyer) with Express postage option selected (default is Standard), and the buyer accepts and payment is processed, the order always goes through with Standard postage option and not Express as selected.
 
This has happened every time I've made offers, I've double and triple checked the offers before submitting them so it's not user error and definitely a bug. I've contacted sellers asking them to send Express but they say the Simple Delivery system won't allow them to change it which is even more frustrating.. Please fix!
