Something I noticed:

I choose a galaxy nexus, and as I clicked between the flawless/good/broken options, it showed me a higher rate for broken then for flawless! Sometimes when switching between two options, the price does not update, so when I get it to show a the highest price on flawless, and switch to good, the price sometimes remains the same.
