Freestyle still has it stocked. I bought a couple packs of 8x10 matte (100) this morning. It looks like they still have plenty of 100 packs of everything else. But get it while supplies last, I guess.

They are low on:
Matte g4 - 8x10/25
Matte g3 - 11x14/25
Matte g4 - 11x14/25 sheets
Glossy g2 - 8x10/25 sheets

But still have plenty in 100 packs.
