I just visited the asset store in unity, searched for toon characters with the highest price option.
So directly compare this stuff
https://www.assetstore.unity3d.com/en/#!/category/20/page/14/sortby/price
and then go to the lower prices and watch out for the quality.
Like this for 40Bugs

Yes I know, it is not my right or job to give other guys some advices
but maybe this could be the answer to questions like "$29 is still too much for such pack?"

Anyway... you are the leader in putting out stuff with the highest prices... but the concurrence is very hard in quality and pricing. Only my personal opinion.
