Trade Market - Spoilers Or No Spoilers?

From the shops I've created, I've obtained a variety of mixed feedback, and some on my use/non-use of spoilers. So I've come to the general public, in hopes of grabbing the majority opinion, to ask if they prefer shops that use spoilers or shops that don't.

 

It depends on the size of your shop. If you have a ton of items, it makes sense to sort them into spoilers so your customers don't have to scroll down 500 lines to the end. Spoilers inside spoilers are too much though in my opinion. And if you don't have many items and use a good format with colors or other text styling, you can do it without spoilers at all for an easier view over all your items.
