Though I am normally a very generous tipper, I used to buy into the concept of tipping deliverers but not anymore! If I am using whole house movers, as long as they're actually working, not messing around/wasting time/chipping my furniture, then I absolutely tip them (especially in TX in warm weather!). But generally I don't tip for regular furniture delivery for many reasons. First, I live in a one story house with a very short lawn. They have to carry a very short distance. I have never ordered anything my DH and I couldn't move ourselves if they'd let us (i.e. if we could pick it up at the warehouse or store, we would), so considering that, these items aren't too heavy...and plenty of times they have dollys to help them along. I also never let them set anything up, I prefer to do that myself and I always clear the area for them in advance. In addition, I never order "sets" so we're usually talking, at most, 2 pieces. I think it's bogus to tip someone for "not damaging" something - that's the worst thing I've ever heard. I have never been that thrilled with furniture companies and their moving companies: they tell you to wait at home from this time to this time (usually a 6 hour time frame), and I have yet to have had a delivery where they didn't show up at either the last minute, or at least an hour past the latest time (with no calls). Finally, When I've just paid $100 to have something delivered (forced to in, in fact, since most furniture stores have to "Send it from the warehouse") I've given my part to the movers (sorry if you don't get paid enough, take it up with your employer).
When did I stop tipping these people? The last three deliverys I've had were disasters (damaged goods, very late, rude, trying to hide damage). Each time I had cash in my pocket ready to give them, and I finally just said "no! they don't deserve it!" It's not that I'm punishing all future delivery people for this bad service, just that I admitted that I was tipping because I was supposed to rather then trusting in my own fair judgement on the matter. It's not like I'm absolutely, "no tips!" If they were to bring in, say, a big screen TV or high volume of products, or if I did have a difficult delivery area (2 stories, removing doors, etc) I would definitely reward that extra huff-n-puff factor. But I don't tip out of guilt anymore. When I finally gave myself permission to trust in my own conscience on these matters, it was wonderful. Next step: not feeling too guilty to send back under/overcooked food!

It's a slow process...
