Here. I took back one I listed before because while they were both rated as 30 MB/s read, one was "Ultra" while the other was "Ultra Extreme." On the other hand, I'm also not doing one like for like where they're both "Ultra" but one is 30MB/s and the other is 15MB/s. The former is probably more fair than the latter. This is from Sandisk's lists, where the same vendor is both offering the card. Note that in some cases Sandisk links to the wrong product, which may have messed me up before.

Tell me if I made any errors.
Thanks for making that list! Grench, I suggest you also spend some time on making such lists (for other brands), it is this kind of information that really helps to get an idea of the reality of prices.
The conclusion for Sandisk real retail prices seems to be: microSD and SD are roughly the same price, but you can get very significant discounts for SD in the higher-end range.
Also note that in this comparison there are no high-speed 64GB cards or 128GB cards because those are not available in microSD.
