Sunday Riley A+ Retinoid Serum

When you think you found a good deal and forget you found it a week ago too, and have dups... The big girl 1.7oz that laughed at me a little when I opened my box this morning with the additional purchases in it, retail is approximately $122 (taken from Sephora.com) for the 1.7oz serum and $85 for the 1.0oz... I have slipped it out of the bag, and popped the lid off of the box to take pictures otherwise no part of the bottle or pump has been touched...
