Yeah. OK. First, let me say that this actually wasn't Amazon's fault, in my view. It's a further testament to the appalling service offered by Royal Mail.
A few days after the GAME incident, I managed to secure another Wii Fit. This time, from Amazon - thank you OneClick(tm)!
Woo. Well. Thats sorted. Amazon are cool, and stuff almost always arrives quickly.
Almost. Not always. In this case, it never arrived at all. Not even after a couple of weeks.
Amazon were great as usual - they apologised and refunded me the total immediately - saying that they would normally send a replacement gratis, but of course, Wii Fit is out of stock, so that option is nixed.
On the plus side, I found out through this process that Amazon's checkout process automatically subtracts VAT if you are in the C.I, which is (to my mind) correct - which is another plus point for them, in my book. I wasn't sure if this was the case or not, as their help is a bit confusing on this issue.
Ordered some stuff from them more recently, and it was sent from IndigoStarFish - their Jersey merchant, and arrived the day after being ordered (at 4pm), despite the fact that I picked "Super Saver". Yay.
Still need a damn Wii Fit though.. Back to the stock checker!
