Prime, Alouette's fairy, is particularly sneaky. You can offer her a reasonable price for an item, and she will reject it, claiming that you are charging her too much. However, most of the time she is lying. Prime will tell you that you are charging too much when she actually just wants to pay less. You can offer her the same price repeatedly, and usually she will eventually accept it. Note: This does not always work. Try selling her items at 114% of the original price until she accepts.
