The books are selling for more than they sold for back then
I was going to say, isn't that much more than the original prices? And I just went and looked and sure enough they were $15.95 and $21.95, respectively.
but the price is definitely cheaper than eBay or Amazon.
Though why do I still get the feeling that there's really no need for her to up the price so much - they're practically doubled! If she had the costs of reprinting them, that could certainly justify an increase, but a reprinting isn't the case, apparently...
