I came across all Braeriach and Jura tartans on Ebay at good prices, sold by Avance Highlands

The Locharron's BRAERIACH is 13oz pure worsted wool for only GBP 30 per meter.

The Marton Mills' Jura is 16 oz/yard, but is even cheaper for some reason, at GPB 25 meter.

Shipping is only GBP 3, no matter how much you buy, evidently.
