Charles, woad dye cannot be sold ready to use, you have to make it fresh, otherwise it does not work. If anyone would sell such to you, you can be sure, it's either not historical or not even real woad.For dyeing with woad, you need woad or indigo powder, Natriumdithionid , ammoniak solution and natron (I hope this translation is correct, i never translated any terms into english).

And for "a couple of tuniques" you will need _lots_ of woad.
Why not buying the dyied cloth? you can order such dyeed with indigo here: http://www.faerbehof.de and at the link above.
