I was browsing through some Scoopon discount deals when I saw that they've got a few in-ear headphones by Monster on sale, which you'll find on COTD as well (same shop).
* Monster iSport Strive in blue for $39
This sells for $98 at Harvey Norman or you'll find it in other colours i.e. orange and black for between $60 and $78 respectively at Wiggle, Boombeats and HN.
* Monster iSport Intensity in green for $69
These are priced at $118 at HN, $169.90 at Boombeats and if you do prefer it in pink Kogan / DSE has the next best price on these at $79.
* Monster iSport Victory in green for $99 or in black for $129
Last but not least this is Monster's highest priced pair of earphones on sale at Scoopon / COTD, but it still saves you over 50% off the next best price at Harvey Norman, who got the green ones for $218 and the black ones for $227.
Unfortunately there aren't any active COTD or Scoopon coupon codes out there to save you the extra costs in shipping, but at these prices I shouldn't complain.
