I used to just buy pjysical books for no reason; now i sort of use Goodreads and buzzfeed books for new recommendations. Then it's just what's more affordable: print or kindle. If i got it on kindle and end up wanting a print copy, i keep a lost in my purse and peruse the used book at thrift stores. Got all the Wheel of Time series and Outlander series (10+ books each) that way for under 25$!
