In reply to MrFlibble:
They've now sold out of the 50m and 60m ropes for Internet ordering. I had to go to my local store (Harlow) which has plenty of both sizes, probably because they haven't got round to putting the discount labels on the shop floor, so it still says £80 on the ticket, but scans as £52 on the till.
Only gotcha is that if you collect in person you have to buy a £4 discount card to get that price. But I got a couple of other things cheap while I was there.
Looks like a nice rope. The python in question must be a reticulated python, judging by the colours and pattern.
