Looking to buy quite a few of these for my new adopted pet. Please let me know if you are willing to give a discount for selling in bulk.

Thanks. :)

If you go to your pets page(https://subeta.net/pets.php) and click on the dropdown menu in the upper right hand corner for the pet you're buying slots for, it'll show you a list. Click on "Treasure" and it'll bring you to a page where you can buy more slots for better pricing.
