I usually never buy shoes online but I did recently from Zappos because they were the same as a pair I already had but in different colours. I would never buy groceries online...that's just too weird for me.
When I bought a camera lens at Best Buy for my girlfriend on her recent birthday, the dumb shit sales punk tried to convince me that the because the lens has a lot of moving parts it was pretty well guaranteed to break and that I should buy extended warranty. It's a $700 Canon lens that's one step down from their top-of-the-line L-series and he's trying to tell me it's junk. Give me a fucking break. Sorry for the excessive foul language; I'm still annoyed from that experience.
That's fucking LAME.
