Oh, I've used new and used before, so I'm aware that sellers try to make the head of the list and get their item first by putting it on at a low price, then whacking on a hugely inflated postage rate at the end. The sneaky little beggers.
This problem doesn't seem related to that though. For example, I now have a novel on my wish list. On the product page, it's listed as £3.70. That's Amazon's price - or at least there's nothing to indicate that it's not. No mention of any third party there.
Below that, new and used is listed as starting from £0.01. The price on the wish list is £1.59. So, unless they've plucked a new and used price haphazardly from somewhere on the new and used list, there doesn't seem to be a connection there.
If it's being sold by another third party, apart from new and used, then Amazon isn't saying so on the product page. Which seems rather underhand to me. And where the wish list price is coming from is a complete mystery as it seems to have no connection at all to any prices listed on the product page.
Other items I've recently added to my wish list show the same price discrepency between the price Amazon has listed on the product page as their price and the price on the wish list. So it's a mystery where they're getting it from. Although, not complaining too much as the wish list price is invariably much cheaper than the product page.
Got Ultraviolet on Ebay, btw! For £8. It could have been much less - there was a copy there for £4 - but that was a Buy Now and I couldn't be bothered waiting for the other auctions to end, so I paid the little bit of premium for convenience.
ETA: I've just noticed that on the product page for that novel, in the top right corner of the screen, there's a box which states 'Usually dispatched within 11 to 13 days. Dispatched from and sold by Amazon.co.uk' - so there's definitely no third party involvement in this one.
