Also "estate sales/auctions" and/or online returns auctions.

A month ago I got an entire king-size bed headboard (with storage), with cabinets on each side, and a bridge that connects the two cabinets across the top (and has lighting - also there is power in the headboard - needs a few upgrades though).

It was made in 1986 - solid wood.

I paid $1 CAD at an estate sale...

Now, the matching dresser with a tri-fold mirror was $175.

Why the difference? No one wanted the hassle of disassembly for the bed unit - but many felt they could probably flip the dresser.

Admittedly, I had to rent a U-Haul (say about $100 including gas) and rope in a family member to help with the move. (because, it had to be at least 800lbs of awkward parts...)

So, my all in was $276 plus some auction fees.

But - still cheaper, more durable and better looking than most "DIY assembly options".

OTOH - if we move again, this sucker stays with the house...

I have had goodluck with this and have gotten many pieces of furniture that will last for the rest of my life used. It is very hit or miss based on your location though and it does restrict your style choices.

At least here, you'll also find a lot of IKEA furniture at those stores as well. Most of the nicer stuff tends to go to higher end stores and ends up being rather pricy.
