I suspect the 'google' search link to a '$9 for a 32G Micro' was inaccurate!
When you go to the page the link takes you to, none of thse vendors listing are offering a 32GB microSD card for even close to that price.
Cheapest on that list is from Amazon ($29.90 incl shipping). The one from eBay ($9.78 incl ship) is for a card reader, not a 32 GB microSD card.
