Back down to one star, RM has gotten rid of the proper online price finder that allowed you to input size/weight/value and see relevant services. Now all you can do is download a crummy pdf. The old system was quick and easy and useful for finding insured services for high value items. Its like these companies go out of their way to employ useless morons to run their websites.
UPDATE: Has improved some what; compensation is easier to get and they have finally adjusted the rates more in line with others. However, still no ability to get normal tracking service from a post office counter, if you buy online with a personal account you CAN'T drop off at a post office! Insane. A lot of online options not available at post office, this is because Royal Mail and The Post Office are two companies due to moronic privitisation. Whole thing needs to be renationalised and run based on customer service not profits to shareholders!
Only use Royal Mail for the smallest and cheapest contents. Their large parcel rates are a joke and most importantly their 'compensation' scheme is an absolute con. The site is a joke - Reference numbers don't work, reCaptcha's don't work (work on every other site I use) meaning it is almost impossible to make a claim. Also be aware that if you are an online seller they DO NOT compensate the value of the item you sold only WHAT IT COST YOU (and you need proof of buying it) - so those antiques you inherited with no receipt are WORTHLESS according to these people. This organisation deserves no sympathy and at the moment I would happily see them go bankrupt.
