Yes and no... often enough, when I decide to get a book, either I've read it in the past or I've read enough about it that I know I want it, so the cover is incidental. On the other hand, if I'm browsing the shelves and deciding between books, then sometimes it does come down to whether or not the cover art is something I want to be seen with (I often take a book with me when I'm out and about, and I'll usually end up on some bench or leaning against a wall, nose in the book as I wait for someone). And since I do most of my book buying at a used book store, it's not unusual for there to be different editions of the same book. Sometimes they're priced differently, depending on the condition they're in, but when all else fails, the deciding factor between one copy and another is going to be the cover art. It just is. xd
