Is it just my area, or are you seeing inauguration merchandise everywhere? E.g., at the Bed Bath and Beyond in the neighborhood here, there was a huge table with Obama kitsch just inside the entry, and then walking back from there (all I bought was plain white sheets), I passed a new storefront set up as "Inauguration Superstore." My personal favorite (just passing by)was the t-shirt with just "OMG" across the front, with the O in the Obama logo style.
I'm sure much of this is because it's DC, but are you seeing it a bit elsewhere?
