In the past I've always had to purchase £15 worth of products to qualify for their free shipping offer. This usually means buying in advance 3-4 books (though I guess it does not matter since I am a fast reader). But now that Amazon UK has reduced the minimum purchase threshold to just a fiver (£5) for customers to qualify for super saver delivery, I can be a bit more flexible in shopping for low priced goods. I guess they are starting to feel the pressure from Play.com (they have free shipping regardless of minimum order).
Below is a list of books that qualifies for free shipping. Yes these are books by Christopher Moore, the genius writer whom you should all kow tow before.
Bloodsucking Fiends: A Love Story
Island of the Sequinned Love Nun (review)
The Lust Lizard of Melancholy Cove
Fluke, or, I Know Why the Winged Whale Sings
You Suck: A Love Story (review)
