Well, I'm just reporting the large increase in Royal Mail Special Delivery prices.
Insurance to £750 appears fine. Remember the extra £2.50 if you took the value up to £2500? It's a tenner extra now.
In my opinion it's still a great service but your typical £2500 of value package is now around the £20-£22 mark. I've never had an issue over 15+ years (apart from some late deliveries). I'm not the only one of course.
