All the US prices are the same, could be a blow out, but more of an inventory reduction then a new model. The store by my place had a deal all last month for $30 off an 8G nano or an 80g black iPod, just trying to reduce their numbers.
I didn't look on Amazon, I meant on the Apple Store.
EDIT: Just realised that they had, gone down about a tenner on the apple store... but the ones on amazon.. fricken bargain! 159 for a 30GB?! If I didnt already have an 80GB now would be the time to get one! (I got my 80GB at a steal at £200 on an eBay store (brand new factory sealed)).
If you search Froogle you can nail an 80GB iPod (ignoring ebay) with free shipping for £205.99 (http://www.ohmac.co.uk/catalogue/index.php?act=viewProd&productId=32). It says 5th Generation, but my memory fails me as to whether there was a 5th generation 80GB iPod or if that was the 60GB and all 80GB are what other vendors label 5.5 Generation.
