Wow Alex you are in a spend mood,

yea mate there are always someone out there to rip you off and relieve you of your cash.
Things aren't always as they seem, and if it sounds to good to be true it usually is.
At least you haven't spent heaps on these items,
Now with your rope, have to agree that Telecom rope can tangle easily, especially at the length you have.
Before you go any further mate, cut it off at 5 -6 meter lengths, burn the ends to stop fraying and you will be right.
5-6 Meters is usually ample to tie down most things.
Take it easy my friend.
