Just to let you know I have created a website to help find the cheapest prices for international delivery which I thought some eBid sellers might find useful: www.parcelquote.net
Originally I was using my own version of this tool just for my personal use but I thought I would put it online in case others found it helpful. At the moment it searches most of the cheaper UK-based discount couriers and about 20 destination countries, but I'm hoping to expand the search options if people find it useful.
This is a new website I have just created, so would also appreciate any feedback about the website in general.
Thanks for your time, hope you find it useful
