Whilst looking around for a copy of the "Cosmos Rocks" 2LP vinyl set less pricey than the 23-25 quid it seems to be going for + shipping, I found this: link
Amazon France has it for 16.23 EUR (13.57 EUR without tax if you're ordering from outside of France internationally).
With shipping for me, it came to 24.47 EUR (incl. shipping for Canada), which works out to be roughly $37.89 CAD / $36.10 USD (courtesy of XE.com) at the moment. It's about $7.32 CAD / $6.98 USD cheaper than Amazon UK atm.
Thought I'd mention that, for anyone still thinking about pre-ordering the vinyl set. Dunno if it's *the* cheapest it can be had for online atm (feel free to mention any other online retailer deals!), but this works out for me as I hate buying vinyl records with expensive price tags.
Your message got me real excited, but unfortunately shipping was way too high for me as well (to Turkey). But I'm sure the shipping will be much more affordable for those who reside in an EU country.
LP's are imported to Turkey at affordable prices though, I was able to stack a few copies of the ANATO 30th anniversary edition for about 10 euros each. I hope it will be the same for Cosmos...
Thanks for the amazon.fr suggestion by the way. I'm sure your message will be helpful for many :)
