You caught us red-handed. Since the 552 package price is $533, and the sum of the items separately is $549, you figured out our scheme to steal from our customers. While we previously used the example of EOTech @ MAP + Dominator @ $134, the ACTUAL formula we used for the package was (EOTech @ MAP + $109 Sucker Charge) + $25 for the Dominator, so you'd actually be paying $508 for the EOTech 552 alone. It was the old ANTI-PACKAGE trick.
Good work Sherlock.
