for 50% less Diamonds today (Jan.28.2014) between the hours of 5 pm and 10 pm
50% compared to when/what?
The first time it was sold? If it is 50% less diamonds compared to the original price, prove to the players that the first time it was ever sold was 798 dias.
50% less diamonds compared to the normal sale price? What normal sale price? We haven't seen these on sale for a long time, perhaps even never (on their own).
The following pertains more to general sale pricing then anything else:
If there are items that are only ever available on special sales (random attribute extractors for example) and they are ALWAYS offered with the same price of X dias, how can you advertise that the item is 50% (or 20 or 30 or w/e %) off? As far as players are concerned, random attribute extractors ARE 39 dias, that is the NORMAL/REGULAR price, since they have not been offered at any other price in at least 1 year. Stop making false advertisements. When you advertise +120% diamond sale, players can go to diamond web page and say "hey normally i get X diamonds, but during sale I will receive 2.2x diamonds, which is indeed +120%". In regards to sale prices we have no frames of reference since certain items, like the permanent backpack slots, aren't regularly on sale and cannot be compared in a similar manner.
