Cuz you bought the chaos pack which is not on sale nor is it promo. The speakers are promo but you didn't buy speakers.
I feel like youre plenty intelligent enough to know those wouldnt count as part of the sale considering they are already prepackaged sales.
Speakers are technically classified as a bonus when you buy the pack. What you are officially paying for is the scimitar.
This is a good point, if the pro packs was on special too they would also mention it, as its only speakers you have to buy them manually. /lock
