Why was the MSRP so high for Ultra Agents sets? I have been looking at the Ultra Agents sets recently and noticed the MSRP for each set is extremely high. Antimatter's Portal Hideout 70172 is around 400 pieces and it retailed for $70 US and Ultracopter vs Antimatter 70170 is 600 pieces and retails for $80 US. Just curious as to why these seem so overpriced.
