I always to for the cheap and cheerful and just make up ingots HQ which sells insanely fast and if you gather yourself, nice profit,sure jewellry sells bit I've put up ingots and it's sold moment I've exited retainer


As for high priced items, it varies, if the market has a lot of it on MB, unless you heavily undercut (bad) it will take a while to sell, on flip side if theirs none or very few, it could sell fast
