We don't collect the fee from students at the elementary, junior high or high school. We feel like it isn't their choice what they've been assigned in school. And if we don't have enough information to do a report, that is our responsibility and not theirs.

So far, no one has even blinked. Most comment on the fact its still a lot cheaper than having to buy a particular book. And we've been able to keep all other services free, except for late fees, and hope to always keep them free.
