Trade website. Forbidden Tome. Problems when buying in bulk.

I'm trying to buy more than 10 pieces at a time. But unfortunately the filter does not sort by area level.



And this is very, very important. This way I get the output of results, including low-level ones, which obviously few people need. It is clear which of the sellers offers high-level services.

If possible, it is enough to add 75, 81 and 83 area lvl. The rest don't matter.
