Yahoo Shopping - why pay?

spidered products vs. submitted products

[Tonearm]

I signed up with Yahoo Shopping and submitted my feed yesterday. Today I'm looking around in there and I see a submitted product of mine at #4 for a search phrase. The thing is I see the same product of mine at #5, but it was obviously a spidered one.

Is anyone here familiar with this service? Why would I want to pay for clicks when I get basically the same thing for free by letting my store be spidered? The only differences I see are this:

1. Maybe *slightly* higher ranking
2. Correct description
3. Correct store name capitalization (MyStore.com vs. mystore.com)
