6-pack Egg Cartons

[berkeley_chicks]

Hello-

I live in the Bay Area and would like to buy 25-50 blank egg cartons that can be spit into 6-packs, like these: http://www.mypetchicken.com/catalog/Egg-Cartons/Pulp-Egg-Cartons-2x6-eggs-p21.aspx

I'd prefer to buy locally and pick up this weekend. I want to avoid the high shipping costs that I'm finding online.

Thanks,
Sarah
