None of the above.

If you want that many kilts you should contact one of the Pakistani kiltmakers. They are all located in the town of Sialkot, Pakistan, which is in the Pakistani half of the Punjab, but on the border with India. Google the location and some kilt related keywords and you should find several websites, but none of them take online orders. You have to e-mail them for a price list and pay them by international money order. Some of them will go as low as US $12 per kilt if you order at least a dozen, which should overcome the minor inconvenience of not being able to order in a few clicks.

I guess I just gave away the big secret of all the budget kilt vendors!

PS: This is where the above-mentionned vendors get their kilts, so it would be silly to use a middle man. That's all they are.

I don't know if they take Euros. They often give prices in both pounds and dollars, though. My guess is they will, because it's all money!
