It transpires that we have been undercharging for Zone 2 and 3 shipping.
Zone 2 was undercharging because of a miscalculation on fuel surcharge by our Fedex agent when quoting to us. It is now £13.16 for Western EU and US/Canada (was £11.86).
Zone 3 was undercharging by £0.35 because I hadn’t plugged it into Paypal correctly: the advertised price was still correct.
All other pricing remains the same.
I apologise for the small increases here. The Fedex system does seem to work out a lot better: instead of packages going into black holes as they did with the postal system, with Fedex they phone me up.
