@OBSHOP wonder if it's less back if you redeemed a free one previously? I still haven't found the Boost version. My offer is labeled as FAO, but not sure if $1.99 will cover it.
I forgot to post the water, thanks for mentioning it. Mine doesn't have scan the barcode on the offer page. It seems if this is missing, it doesn't go through. I'll try later today and see what happens. Maybe it will work this time around.
