Tried it once because I couldn't help myself and got the Garden Pavillion. I haven't been this lucky with all the boxes that were on sale until now :P Always got multiple repeats of 3rd/4th place prizes and ended up giving up.
this is why i commented on how a 20% discount wasn't was it used to be. 1) reduced gem earnings from downloads by 33% and 2) potential lack of recipes (someone would need to check though).
so yeah, atm, a 20% discount in my eyes is like paying full price a year ago...
