RPi OS – preloaded microSD for Raspberry Pi

This is $20 before taxes and shipping, it doesn't even seem to tell me the capacity of the card, and I have no idea who's behind this. Why would I buy from here, rather than from an approved Raspberry Pi reseller, that does tell me the capacity, for half the price? E.g., https://www.okdo.com/us/p/raspberry-pi-noobs-preloaded-micro... or https://www.canakit.com/raspberry-pi-sd-card-noobs.html?defp...

EDIT: Okay, I found the capacity (32GB). But the only way I've found to see it is to right-click Open in New Tab on the Buy Now button and then hit the X in the top-left corner. I don't think that it could be any less intuitive. (And when I do this, I now also see the manufacturer of the card is "Everything But Stromboli", which is definitely not a name brand.)
