I mean, they are pretty great boots - you should definitely finish the purchase you were momentarily contemplating.

I especially love when the email says something like "hey, that shirt you clicked on will be out of stock soon ... better get it now." Even better when its a staple product and/or will end up on sale - though, that's one more chance for them - "hey, remember that shirt you looked at for a couple seconds back in January? Yeah, well, now it's $1 off - so, better buy it."
