They were under $1 each in packs of 10.
I also found these (below), after I had ordered the above fets.
Mosfet Type: P-channel
Current Rating: 2.6A
Rds (On): 40 mOhm
Voltage Rated: 12V
Package: SSOT-3
Mosfet Type: N-channel
Current Rating: 4A
Rds (On): 100 mOhm
Voltage Rated: 60V
Package: SOT-223
They are smaller package, but probably suitable for my 1 amp needs. they may be suitable for 1.3 amp, you have to check.
Im not sure which one I got it from, thaishine also sells through ebay.

I am way behind on those cubes, and I havnt had a chance to use the parts, but I assume they will be good for cubes/multiplexing.
