Fantastic service. Others in this thread have correctly identified that 90% JBV is a low payout compared to shipping to a hub via PUSHX/RF, especially if you’re willing to sell order instead of selling to buy orders, but that’s missing the point. HSBB is an unbelievably fast and convenient way to sell, and that comes at a cost. For me, the ability to dip into a nearby highsec island and instantly lock in my exploration profits to keep my lossmails small is 100% worth the ISK.
HSBB charges a premium that sets high expectations and absolutely meets them. It’s not right for everyone, but if you know what you’re getting and how much you’re paying for it, it can be extremely useful. I strongly recommend it to anyone who values convenience in their gameplay.
