These speakers are £99.99 from Bose direct (2-3 week delivery time depending on your colour preference) and sold out pretty much at every reputable Bose stockist (Currys have limited stock at £86.99 in some branches, these being ex-demo stock) and those that do have stock are selling at £99.99 rrp and more than that in some cases.
I purchased my one via the Apple Store app on my phone and had it delivered to their shop in Stratford Westfield, from clicking the buy button to picking up my purchase was less than 48 hours.
Very pleased - I'm pretty sure this is the cheapest price for brand new stock that's readily available (I.e. Unlike Amazon who only have the Mint version available for delivery in 2-3months time, again listed at £99.99).
With regards to sound quality? Loud for a small speaker and seems to be reviewed well.
