I received my B12 order from iherb today, which was only ordered one week ago, pretty quick with no problems with customs at all, they opened the box but did not break the seal of the bottle container.
I got the " Natural Factors " brand, 90 x 1 mg tabs, being that our customs only allow 3 months max supply [for 1 person] and that's going by the manufacturers daily recommended dosage, which is one per day with that brand anyway.

Price wise, its extremely cheap at $10.47 [US] & $4.00 [US] delivery [USPS first class International]

This compared to our compounding pharmacies that one wanted $58.00 for 30 x 4mg b12 Methyl tabs and another i contacted that wanted $88.00 for the same, without delivery costs.

So for any Aussies thinking about getting some, this kills our prices by far, seeing most chemists want about $17 for Blackmores 1mg Cynnocobalamin.
