I can understand the getting them up part... but I'm talking about full-blown, keeping-up-with-the-Jones neighborhood displays.
Way too early for that. Once the turkey is out of the over, you can do whatever you want.
The shopping? Well, sorry, but that's just corporate greed. It's all about $$$ to the retailers. Do you think any of them care if you're happy on Christmas morning? If so much of their annual sales are based on the holiday shopping season, maybe they need to find smarter marketing people to get us to spend our money in June!
