Currently there are two signs at shop you can sell levels at. The bottom sign only allows you to sell 165 experience points at a time. Which, you can imagine makes it very tedious to sell levels when you've been saving up. Since all the other signs at /shop allow you to shift click and sell your whole inventory, I feel there should be a similar shortcut for levels. Even If it's not a shift click/instant sell. The top sign allows you to sell levels a tiny bit quicker, but gives way less money and still isn't very efficient. My suggestion is to replace the top sign or add a third sign to bulk sell levels. Example: 165k experience points for anywhere from $200k to $225k, this would make it a lot easier for those who save up their experience points to sell them at a fair price.
