seller cancelled after I won an item as they wanted a higher price

[chunky_pegrum]

I have just won an item, but as I was on the payment page it said there was an error, when I refreshed it said the buyer had cancelled the order.  When I emailed the buyer they stated that they were expecting a higher price and that they would be willing to sell them to me for a higher price.  What should I do?

If they have Cancelled and you can't Pay there really isn't anything you can do other than Leave Appropriate Feedback. 

I would go and find a better Seller. The one you describe is trying to coerce you into trusting him a Second time, when he could pull the same stunt again.
