I'm not sure if this a glitch or something I have set up wrong on my listings.
I have had 2 orders in last few days for the same item (Item : Large Hanging Rainbow Crystal 40mm Sphere Ball Suncatcher Feng Shui Item ID: 103285651). Both buyers paid immediately via Paypal but have not added the postage cost.
The listing looks OK to me, but I don't want to contact the buyers about underpayment if it is my fault. Doesn't the postage get added automatically when the buyer goes to pay?
Any clues?
