As Groupon let us all down big time, I thought I would post this.
Click link for full details. Plus there are lots of reviews (youtube etc.) out there - just google it.
Don't forget, you cannot compare this to the Groupon deal, as the Groupon deal never really existed!!**UPDATE**
big thanks to littlelow - O2 deal is better than Costco deal - subject and link updated to reference O2 deal. Please credit littlelow for finding this deal at O2. Be aware O2 price shows as £199 until you add to basket.
OK so will not let me change link, click here for O2 deal...https://www.o2.co.uk/shop/accessories/harman-kardon/onyx-studio-3-bluetooth-speaker/
