I sell framed photographic prints worldwide, so have been using the three comparison sites to get prices for international couriers.
My first price was £22, then a while later it jumped up to £30 and today it's £55. Difficult to sell these with such fluctuations in prices.
So does anyone know who can you can contact to get a set price on international parcel delivery? Most of the couriers are just brokers, so can't fix a price.
