No doubt about it. You can't buy everything online, but each online order is one less trip to the mall or big box store. That means that all those impulse buys that happen when you wander into other stores "since I'm here anyway" go away. Out of sight, out of mind.
I wish that were the case with me: it seems like nothing’s ‘out of sight’ on Amazon!
I have to seriously restrain myself; you’ve no idea how many things I never knew I needed until they showed up as ‘suggestions’ online ;-)
