you can redeem more than 100 points worth at a time (ex: 2 gifts, for 200 points...)
There have been times where I accumulated more than 500 points and didn't select any of the deluxe samples bc I did not like them, but if I found one I liked, I could get multiple. Last time I got 2 of the benetint...I don't think you can stack more than 1 online though
This is good to know - I have over 500 pts right now because I bought a GHD for my DD, and had some that were not redeemed in the store because I didn't like the samples.
I'm about ready for new stuff too!
