A few days ago, I typed in 'Thomas the Tank Engine, new'.  Great, up came 4 pages of what I was looking for.  Found one that I was interested in.  Got interrupted, and so when I typed in the same search criteria later, there was about 20+ pages.  I never did find the 'right' one again.

I can't understand why, when using the same words in search, that a completely different lot, and quantity of listings come up.  And no - the rest of them weren't 'new' listings.
