How many boosters are in a box of modern masters?
24.
If you want to buy a box, the cheapest I've found is 240 at dacardworld.com, just bought a box and they give you a code for 5 dollars off and you can choose a free gift, I got two free ugly frost giant playmats, haha. Less than 10 bucks per pack though, so meh!
I wish I could get a box of mma.:( so expensive but so many good cards!
