Did you see the roots actually take or just rot?

Used to buy every little pack too, then realized I never touched half of it. Now I just wait and only grab stuff I actually want, way less regret that way.

Ha, so you invented a spreadsheet to stop yourself from buying books you don't even want. That's a very fancy way of saying you finally started reading the titles instead of the price tags. The doubles thing really got me though, buying a book you already own is a whole new level of "oops." My rule is I only buy it if I can name one person I'd lend it to, which has saved me a lot of money and probably a lot of shelf space. $18 a month is solid, now the real test is whether you still hit both Goodwills every Saturday or finally got your weekends back.
