I don't understand why a lot of people go through the sort of run-around described in many of these articles. If you order furniture and it doesn't show up on time, you give them a hard deadline of a week or so to get it to you or give you a refund. If they don't cooperate, you charge it back on your credit card. If you order furniture and it shows up damaged/missing pieces/broken/etc., you call them once and tell them to make it right. If they don't immediately give an acceptable response, you tell them that they'll make it right or you'll charge it back. If they don't make it right, you charge it back.

The only thing you have to keep in mind is the 60 day limit that most CCs have on chargebacks. Since furniture sometimes takes a while to be delivered, you just need to be sure to initiate the chargeback on day 59 if there are any issues remaining. You can always withdraw it, but as soon as that clock runs out, your leverage is gone (you can still go to court, but the threat of a chargeback is a better one because it's so easy for you to do any costs nothing).
