And all fiefs have all gear at -2 loom level (two red small v on the top right). Don't buy those, but buy loomed gear only. Most fiefs have discounted items as well to make them cheaper.
Quick tip, when you buy equip for an army, go with around 30% of each melee class and 10% ranged. It's a bit too much, but you usually have enough gear for everyone. For example if you have 200 tickets, make sure you have around 60 1H, 2H and Polearms and 180 heavy or medium armors.
