Where to find the best deals on SDHC cards?

I’ve been scouring the web, no luck so far... it turns out finding the exact card I'm looking for is harder than it should be. Apologies if this feels a bit out of place—I know an SDHC card isn't exactly a CPU or a high-end GPU, even if you end up plugging it into your PC. But I'm specifically hunting for an SDHC card with built-in Wi-Fi.

Long story short—it’s a card with its own little Wi-Fi chip inside. Once you snap a photo, it just automatically beams the image over to your laptop or your phone, depending on how you set the thing up.
The reason I'm bothering you guys here is because, honestly, people on this forum actually pay attention to hardware prices and niche components—stuff that usually falls outside the usual PC building scope.

So, what I need is a Wi-Fi enabled card, 8GB, SDHC, Class 8 or 10. I really don't want to settle for anything lower than that...

I'm not even sure if they even make these in an 8GB format anymore. Is it even worth hunting down such a tiny card when they end up being pricier than the standard ones?
Take this 32GB one, for example.
$133

compared to this 16GB version.
$126

It’s pretty obvious that the built-in Wi-Fi is where the real cost is, not the actual storage. I mean, why wouldn't you just grab double the capacity for basically pennies more?

Go ahead and grab a SanDisk drive then get to work, 🙂 though I have to say, they charge an absolute fortune for them.
