You posted that they had "almost nothing" when you searched for Christmas, and the fact is, they had 7,900 or so items in that category (did ya *click* it?) and, I might add, the store itself is overflowing and bursting at the seams with Christmas stuff.
This is so much tilting at windmills. It's comic. Really!
And it is probably some kind of standard function programmed into their search engine - i.e. when a search returns an unmanageably HUGE number of results, suggest something more focused first, as a way of encouraging them to refine their search term a bit more. It doesn't happen when you search for "Christmas lights" or "Christmas tree" or "Christmas story" or...
Of all the things to get bent out of shape over. Sheesh!
