I am lucky enough to live about a half an hour away from Bronner's Christmas Wonderland, which is the worlds largest Christmas store. They sell anything possibly Christmas related, thousand of ornaments, lights, garlands, trees, gifts, nativity sets and collectibles. This is THE Christmas store if you are looking for a hard to find item. This store is so huge that you seriously could get lost in here, and spend hours looking at stuff!
This store is open year round, although we usually only go there around Christmas time. I am excited to take my daughter there this year, I think she will love it!
They also have a great online shop with a huge selection of their merchandise, including their awesome personalized Christmas ornaments.
