Wait and you will return only when the 500 points prize ends and is updated

I have been collecting points as much as possible recently to get a $2 coupon, and there was only a 10-point difference. But now this coupon is no longer available, and I am worried that when I collect 300 points, it will end as well, because it has a limited number. Once it ends, it will no longer be available, so I am collecting as many points as possible, at least 500 points, to be safe.
