First off, a little briefing for those who are unfamiliar with Touch of Modern: the site requires an invite to gain access, so if you're not already a member and you're thinking of buying this, or any other deal really, you should sign up for an invite immediately. I got mine in a day or two after requesting, but your mileage may vary.
With that out of the way, the Braven 600, 650, and 625s are all on sale for 20% off right now via the site. They're currently running for $120 for the 600 (normally $149), $144 for the 625s (normally $179), and $152 for the 650 (normally $189). When David reviewed the 600, he found it so impressive, he wondered just how much better the higher-end versions could be.
The deal will last until January 1st at 12PM EST, so unless you already have an account, you won't be able to order today, but sign up and watch your inbox for your invite. And even if you don't want these speakers, I recommend inquiring for an invite anyway. This site is fantastic and frequently has great deals on all kinds of fancy and eclectic stuff.
