The Apple Store UK is selling Mac OS X Tiger for £90—that's equivalent to $US170. The same product on the Apple Store US costs $US130. Yep, that's what I thought... but it's not quite worth a flight to New York. So what can you do if you live in the UK but want to get Tiger at a more reasonable price? Well, you can...
...look to Amazon.co.uk, who are selling it for £75 ($US144). It might not be equivalent, but a saving is a saving.
So if you are in the UK and want to save £15 on Tiger, please click here to place your order and in the process you'll be supporting this site ;-)
Bugger!
