b/c you can't get the label made by____ or [exceptional] or [blessed] anymore. The more desirable the item with these labels the more money it will sell for. A pair of [blessed] boots can easily range 5-10m, a pair with that tag and a made by tag can hit about 15-20m. A kilt with a [blessed] tag will usualy cost about 5-10m, skirts about 5-8m, doublets about 15m, etc.
So, 30m for these boots, possibly even alittle more isn't out of the ordinary.
