Search has 6 sort options. Here is an example of the initial results of these sorts when searching for Collectibles postcards new year:
Best Match 86,000 results.
Time: ending soonst 76,000 results
Time: newly listed: 76,000 results.
Distance: nearest first 76,000 results.
Price + Shipping: highest first 76,000 results. 6 results less than $1, 49 $1-$1.99, and 686 $2-$2.99
Price + shipping: lowest first 402 results. No results less than $1, 1 $1-$1.99, and 3 $2-$2.99
So the initial search by lowest first only returns 4 results less than $3.00 and none of the lowest results less than $1.00 vs. the 741 results returned by highest first. The initial search has a message: "We've streamlined your search results to show you the best listings. See more results." When you click the message link you get 76,000 results. So for this sort to actually work and show the lowest priced listings you must always click the link to see more results.
