Light Armor Kits - Sulfuras US.
I've been making Light armor kits and selling 4 at a time for a total of +32 Armor for 2 Silver. I think it's a pretty good deal.
Sure, they are all over the AH, but I've managed to get multiple people to buy from me. =]
Okay, so I primarily sell slightly above the default price when placing an item up for auction.
My focus here is mostly for my LAKs (Light Armor Kits) which give +8 Armor per kit, which you can use a total of 4 at one time to give +32 Armor across Chest, Legs, Hands and Feet.
I looked them up and saw only x1 LAKs were going for 1s 10c..so I figured 10 LAKs should sell for 10 Silver if the going rate is only 1s 10c per item, this is essentially cheaper than buying the 1s 10c if you plan on buying 10.
