Yes, and it was more than I made on my first payware for the sim... several grand. I believe it was purchased through geowgs84, but don't quote me on that. It's been several years now.
Honestly, unless you plan a few projects in the coverage area you buy, (in my experience) it's not really financially worth it. Use USGS, Earth Explorer, or a local gov source if the country has it, or just rely on the in-sim Bing data and know it may eventually change (for better or worse).
Optionally, you can also go pretty far with using aprons with custom tiling textures if the surrounding Bing imagery is half decent. I've only tried it for backcountry though, which is easier to blend. Not sure how it would look for a larger airport, but maybe with the right textures..
I'm even doing a bit of that with this airstrip.
