If you buy it today RetailMeNot has 16% back from HSN, that will change tomorrow, could be lower or even higher.
I bought the 2 oz while back, not tried it yet, I know I got a very good deal, but this is probably better. I am not usually fond of facial creams such a big size, I like trying new things most of the time. the $5 off code should work on the TS. TS price is up since yesterday.
