See a book, like a book, buy a book
Yeah, one week you're walking the streets that Dante trod, and the next you're strolling down the aisles of … Costco? Yeah, Costco. That's where I was earlier today, buying a pair of books that look particularly interesting and a berry smoothie — all for less than $20.
And, no, I don't feel guilty. I've spent plenty of money at independent bookstores all over the world. But the sad truth is that when I see a book that intrigues me, I just have to buy it.
