Singtel mio tv is sweetening the deal. Looks like they will soon bundle channels. The first was BBC 3. Now it is the VOOM HD channels.
Now, instead of paying S$12.96 for a single HD channel, you can choose to subscribe to the three channels in a pack for $19.26. Usual price for the 3 channels would cost you S$38.53 per mth.
The catch is that you would need to subscribe it for 6 mths.
Just in case you are not aware, the 3 channels have some overlaps. Some SlingHD programming and Equator HD programs do appear on VoomHD and vice versa.
