These are pretty rare, but the demand for them isnt that great. I managed to get an angelic raiment [max curse] for 3kce (that might be a bit cheap for a max though). Although it was months before finding it, and I had given up on it, someone saw my dead thread and offered it to me at that price. Perhaps lower your starting bid to 1.5kce, and you b/o price to 4.5kce or something along those lines. If someone is after that uv theyll pay it, its pretty rare.

Yeah, i know its Seraphic Mail and took that into account. However, I forgot that angelic starts on 3*, not 2*. My bad. Thats just going to make it harder to sell, since 7kce b/o is way too much for a Curse High. When people are looking for uvs theyll usually look for the lower stars and avoid unbinding costs altogether, so this isn't really an easy sale (as you've noticed). I think 5kce is an optimistic b/o. The price has to be right for the buyer and yourself, so if you really cant bring yourself to sell below 3.5kce, you'll have to hope someone wants a curse high enough to offer that. You still have your right as a seller to not sell the item if no-one bids to your reserve price in mind.
