So I have a couple of chests full of Horse Spawn eggs and want to sell them. I placed a slot sign charging 40r each for random horses less than 100 speed. I can only make 1 sale before it starts telling people that there are no items to sell. If I place a regular shop sign it doesn't sell any. Now, I know why it happens and have figured out a workaround using hoppers and dirt blocks, but I want to know if there is an easier way. I once bought 3 donkeys from a shop and all 3 had the exact same stats, is there a trick to doing this?
