First of all, I apologize if the answer to my question is blatantly obvious or if the answer has already been answered countless times before and is easily accessible. I'm a noob, so forgive me.
I noticed in the settings for Abrosia, if you were an advance member, you could check off the box that says "purchase items not found in item database."
As well as the option to "purchase unknown items first."
While running AB in the shop of my choice and getting RS banned, I had the settings to continue at IGS. What caught my attention was that the ABer was buying a lot of seemingly "nooby" items, one for example, "Basic Mint Floor Tiles."
I checked with the shop wizard and there were none in circulation so I deduced that it must've been a new item of some sort.
Now the million dollar question here (perhaps 1 np?) is whether or not it is recommended, when considering the profit in the long run, to keep the "purchase items not found in item database" checked.
Since I don't even know what to compare the new items to, I am at a loss to even the amount the item such as the Basic Mint Floor Tiles should be priced.
Thanks in advance for all your helpful input!
...and forgive me for being such a novice.
