It's my understanding that this is not a non-profit organization, with books being re-sold online at a profit, a tiny percentage of which ends up being donated to non-profits. I'd simply advise people to do their homework and decide for themselves if this is what they want to do. Local bookshops on Moody Street, one a non-profit and another a for-profit, both accept donations. My personal preference is to support these enterprises, thus supporting local organizations and businesses in Waltham.

Thanks for mentioning that! The big advantage is the pick-up. Perhaps some boys and girls could organize a "book pick up day from and to Waltham" to get the books to the Waltham Book stores!
