Browsing for prices on Amazon, I came across something that simply stopped me right in my tracks - almost £2000 for half a gig of PC133 for a desktop! (wasn't after it for a desktop, was looking for prices for PC133 SODIMMs);
Don't want to pay that for half a gig? Then you're definately not going to like this one;
There is of course, a serious point to this. There's been quite a few cases of online shops mistakenly selling things for less than they meant to, and that's obviously a good thing for the shopper. However, unless you're actually looking at the price before you click through to purchase, you could be in for one hell of a shock.
