Finally found the dimensions of the large box --> 12 x 12 x 5-1/2
The "regular" box comes in a couple of versions: 11" X 8.5" X 5.5" OR 11-7/8" x 3-3/8" x 13-5/8"
I haven't experimented with putting books in these, but my hunch is that it's hard to get the 17 lbs. you'd need to make it more cost efficient than the m-bag. But maybe for Australia where the m-bag rate is more expensive.
For the UK, a 20 lb. m-bag would cost $57. A 17 lb. is $48.45 -- pretty close to the rate for the flat rate box. And the m-bag is charged per pound, so as soon as you're over 17, you're in the flat rate box territory.
For Australia/NZ, a 20 lb. m-bag would cost a whopping $90. Just 11 lbs. costs $49.50 -- the minimum m-bag cost.
So if 11 lbs or more of books can be crammed into the large flat rate box, it seems like a good way to go...

According to the UPS website, the other one 'left the US on 5/3' !
