I'm one of the lucky ones in that I have enough of the original K-Sigs to last about a year, depending on how bad I play this year
Fortunately I ordered some before all the "hype" and after playing them once, I ordered more (and managed to snag a few the final availability, as much of a fiasco that it was.)
Hopefully Costco returns with more, either the original or the speculated new Kirkland ball (and if new, it is a good replacement based on price/performance)
