So, as I understand it, the price you pay for a book in Britain or in Europe is, in some part, a subsidy to keep the small stores from going under. There are both problems and benefits with this...but that's what you're paying for.
The only reason I posted was that I clicked on Michaels link to Amazon US and saw it was List Price: $44.99
Price: $29.69 & this item ships for FREE with Super Saver Shipping. Details
You Save: $15.30 (34%)
and I thought great I'll have that, went to AMZ uk and saw it was £28, in my annoyance I dashed off the post which I stand by, I have now calmed down a bit and revisited
AMZ UK and found a link to one of the importers advertising there. I can buy it imported from USA for £15.17 with £2.75 postage so contrary to my rant I am going away to order a copy. You will no doubt be relieved to hear that, the going away part I mean.
