Kirkland (Costco) adult diapers for postpartum?

This will be my second birth. After my first, I bled for an entire month, and very heavily the first week. I used the Always Discreet adult “underwear” and they were great! But pricey. I’m in Canada, and a 32-pack of Always Discreet is $25. I was at Costco the other day and noticed their kirkland brand adult diapers are $39 for a pack of 84!

Has anyone tried them?
