So I will share my stories of how I have found a few trees so far!
I went to the Rescue Mission and found this tree for my breakfast room.
It was a pre-lit tree and they were asking $20 for it. We tested to see if the lights worked and since they did not, they marked it down to $5. I snatched it up knowing I could just add my own lights. My sweet husband cut off all the strands for me! We re-strung the tree and added red and green ornaments. Pretty awesome for only $5, don't you think!
