For anyone unaware medium stars were briefly on sale for 75% off and now for 33% off.
This is a pretty big mess up, especially considering neither sale was communicated to the players as of yet, hours later. Sales should really be communicated ahead of time or at least at the time they are activated.
This also doesn't inspire confidence as a consumer. Just imagine if the situation was reversed and how ripped off anyone who went for the 33% off would feel when it later gets bumped to 75%.
I do like oddments sales, but they need to be done and communicated in a better way.
