I believe, from another thread, that the basic fee dropped recently to six dollars. The ones I've seen have all been six dollars, and then, if they didn't get any takers, they started to add a bonus. So, I suspect that you did them in the past, 'knew' the fee, and didn't notice what it actually was.
I just did a seach with a 999 mile radius. Looks like a lot are $10 dollars, some are 6, one is 30. Note that they're due today, so it's plausible that bonuses have kicked in.
