Also can't be sure if there's anything rare hiding in the piles, but if the seller singled out the illustration cards then probably not. You could probably have gotten them cheaper with some patience and luck until recently though.
The other two... yeah I don't see anything that would warrant that price.
Speaking of overpriced, someone has been putting up a lot of the old Konami Collection cards of the original Suikoden but single cards at prices that would have gotten you a dozen or two just last year. Someone's hoping to cash in on the boom of Card Stories.
You could get into without having to spend too much, starting from 0 you could get a lot of common cards easily and without much money put in, but pretty soon you'll be at a point where the only cards you're missing are rare and expensive and even then most collectors would be reluctant to sell them cause they have more value for trading with other collectors.
