This might be of use to people who don't want to buy cables at rip off prices.
Ordered a 10m HDMI cable on friday night, arrived tuesday christchurch > hamilton. It looks like its good quality, around 10mm thick so its well insulated i'd say.
Ordered a 10m optical cable on monday night after getting a stock confirmation (if the quantity is below 10 they do a manual stock count), arrived thursday. Quality looks good, and it has caps over the ends to protect it when its not plugged in.
Would recommend to anyone wanting cheap cables.
