Target. I get there, and they are completely out of trees, decorations, everything. The lines are long, even at 9:30pm! And people in the parking lot are inconsiderate - taking your space while you've been sitting there for AGES with your blinker on waiting for a space. I normally like Target - but during the holidays it's hell.
On the flip side, Frank's is great - I got my tree there for under $20.
