Seforim!

I recently discovered buying seforim from a seforim gemach, or certain seforim stores that sell seforim outside their store for very cheap(boro park). Most of these seforim are in great condition or even new! Many places you can just get an extra Mikraos Gedolos, siddur or any other expensive book/biography which you would usually never buy at full price for only a dollar.
Why would anyone want to buy new books at full price anymore? I actually realized that when getting these books/seforim at such a low cost it actually makes you want to use them more as opposed to buying brand new at full price. I think the reason is that when people get a brand new book they paid so much and are afraid of ruining the condition of it, and it hurts to see it worsen. In addition to that most people buy so many brand new seforim at full price and are lucky if they even open them once before leaving it on the shelf for the rest of eternity.
Besides most of these gemachs have the money go to a Tzedaka like Tomchei Shabbos or something so its a win win situation. You continue the legacy of the sefer and give tzedaka for it.
So anyone still intereseted in buying new?
