I also sell enchanted and repaired tridents. But I thought (and sales have confirmed) that some people would rather enchant them themselves.
I sell maxed-out enchantments, but that isn't necessarily what everyone wants. A couple of examples:
- For trident golf you would ideally want Riptide I, II, and III, not just III.
- The enchanted tridents I sell cost 8 levels to rename. But if you leave off some enchantments you don't need or get some enchantments through the enchanting table rather than books & anvil, you can get a lower rename cost.
I don't think it's practical to stock every combination. Some of them would end up not selling, and the inputs (tridents, enchanted books, and experience levels) are very time-consuming to acquire.
Finally, I'm not asking for a new feature here. I'm pointing out that the behavior has changed for the worse in just the last few days. I'm suggesting reverting to the previous, more useful behavior.
