My question to Google was:

Subject: Cheapest Product?

Hello Google,

What is the cheapest product you sell?

Thanks,

Hi Philipp,

Thank you for your note. We're always working hard to help you easily find
what you're looking for with Google. While we don't provide personalized
search assistance, we can offer plenty of tips to help you search more
strategically.

First, choose your keywords wisely. Select descriptive, specific words.
For example, [ 2004 football statistics ] rather than [ football ] or [
Vancouver 2010 Olympics ] instead of [ Olympics ].

If you're looking for an exact match, try a phrase search. When you
enclose your search query in quotation marks, you'll only get results for
the exact terms you entered in the order you entered them. For example, [
"friendly robot" ] rather than [ friendly robot ].
