I would have gone for grocery gift cards but it might be best to wait for another 30% off sale? Based on the cadence of the last 2 sales, it may not be long before they have another?

If I am able to get 30% off WISH cards, a calculation from another ozbargainer shows that 130k points would render $875 in gift cards. But redeeming outside of a 30% off would yield significantly less points than this.
For flights, I don't personally see value in business and first class tickets and booking with economy seems to be difficult/undesirable due to taxes and availability of fares. And in case you are curious as to why I don't like business class: it's because I don't want to spend hundreds and hundreds of dollars extra just to be in a slightly comfier seat for hours and for a few cheap heated meals/biscuits/drinks. The airlines make higher margin on these seats and they are worse for the environment because it reduces plane capacity.
For economy flights, I see Bali Jetstar reward fare is 18k points each way plus $128 and $91 in taxes, so total of 3,6000 points and $219 return.
This is ~OK but in the Jetstar sale right now, I could just pay cash for the whole fare and get the thing for $337 return and zero points required.
So for my needs, the best bet may be to wait and see if another gift card sale comes along?
Yes, in fact, some would say it is 30% less.
