No problem

I reckon the prices went up (although arguably, minimally) last week as people were making use of the free buying. I got mine for just over £68. I think you would still be able to get them for around £80 (fee inclusive) if you keep checking the prices everyday. I found it helpful to look at the graph as they can fluctuate a fair bit throughout the day as well.
Have you ever considered investing in AP's? I don't know whether an AP (Dream) and a room only holiday (SH discount of 20%) would work out better than just going with a discounted package...
