Maybe we can put a list together. Many books don't allow this at all, or overcharge like Pinny (for theory behind buying 1/2 and full pt see the book 'win more, lose less').
The Greek charges 20 cts for the first 1/2 pt, plus another 20 cts if you want to buy the full pt through 3.
Youwager charges 20 cts, and then 10 cents for the full pt through 3. So if -3.5 is -110, then -2.5 is -140.
