Ahh, the extra $-2.50 off was part of Amazon's daily "Gold Box Deal" promotion they had applied to my purchase.
My Order Summary listed:
Items: $49.99
Shipping & Handling: $6.88
Gold Box Discount: -$2.50
Super Saver Discount: -$6.88
Total Before Tax: $47.49
Estimated Tax: $0.00
Order Total: $47.49
**Update**
Confirmed the price is $49.99 out-the-door. A buddy at work just got one as well, but did not get the additional $-2.50 discount. I've edited the thread title
