The link got erased but I think I saw those when they were on sale. Was one of them a fixed week New Year's week (~477 points IIRC)? $60K is a pretty big expense, but for those who want low dues and are ok with the 7-month window (or just want to go to Oahu often) it gives them a decent amount of cheap currency. It's easier to spend the money in smaller chunks, but it does add up regardless of how long it takes one to accumulate hundreds of points!
It's tempting to think that paying an extra $30-$40 per point is not worth it because you save $2.3/year so it takes ~15 years to "break even". I find that somewhat of an oversimplification because the extra expense upfront of $30-$40 per point is not really unrecoverable. If the person sells the contract 10 years down the road, they will still sell it for a higher price than a non-subsidized contract (maybe still $30-$40 more) and, in the meantime, they paid lower dues for 10 years. Don't forget that, with a 25% dues discount and with dues going up annually, the value of the subsidy also increases annually in dollar terms. For example, if Aulani dues were $12/point, the subsidized dues will be $3 less - so now paying a $30/point premium is only a 10-year "break even". Ther is a lot of value in 40 years of subsidized dues...
We did buy a subsidized Aulani contract (mostly for 7-month bookings) but only about 200 points. If I lived on the West Coast and visited Oahu more often, I would have considered that 400+ point purchase and would have been willing to pay the asking price. But, despite my handle, we're on the east coast now and Hawaii is a rare trip... We also tend to prefer Kauai over the other islands.
