Buying off the 3

Buying off the 3 One of my books lets me buy on and off the 3 for 15 cents. Should I be doing it everytime?
in the nfl yes always and buy through also if you can buy more than 1/2. buy 3.5 down to 2.5 and 2.5 up to 3.5.
Regular season yes everytime, for preseason though the 3 isn't worth as much.
We have never bought points in 50 years of betting. If 3 is WA, we usually can usually get 3 1/2 with a local. Fezzik is the authority on this, and I suspect he would advise buying. We just keep shoping. Often you get an extra 1/2 or one point right at post when books have all one-way action on the favorite.

It's somewhat marginal in NFLX, but prolly still worthwhile if it is a bet you would make anyways. In regular season, it's so good that you might want to consider making bets you would never consider otherwise, especially if you can buy through the 3 for 30 cents.
