they probably stated values up to $120.00 (to cover themselves) and a moda fat quarter can cost up to $3.50 each and a 6" charm pack is usually around $12.99 to $13.99. the 5" ones are just over $10.00. since each got a different number of fq's and charms, i would think these were clearance items.
i do believe that craftsy would have made sure that the value of each person's mystery box would have at least been the $60.00 they paid for it or they would open themselves up to many problems i.e. deceptive advertising
