Much better than gambling on getting some random cards!
So math wizards, can you add the 20% to your present level discount to get effective total discount?
ie., triple diamond 45% + 20% = 65% --- Am I doing my math correctly ?
So we get 100 / 600 = 0.166667% rebate.What I meant is 100 / 600 = 0.166667 = 16.6667% rebate.
Card is to play a game of chance when such games are available. Since the probability of wining is not know it is impossible to calculate the expected value of a play. Based on only my experience the average cost of a Special Event Card about $15. This is not very accurate because it is the average of what just one person, me, paid for a total of 6 special event cards.

not Exactly.. The % discounts Add together, but you have to figure each out seperatly..
100% - 45% = 55% so you pay 55% of the normal cost.
25 x 0.55 = 13.75
if you bought 500 credit for $50
$50 / 500 = 0.10 per credit
13.75 x 0.10 = $1.375 for the card
now you got an extra 20% on the credits you bought.
500 + 20% = 600 credits for $50
$50 / 600 = 0.08333 per credit.
13.75 credits * 0.08333 = $1.1458333 for the card which normally would have been $1.375
So the extra discount is
1- ( 1.1458333 / 1.375 ) = 0.1666666 or 16.6%
Not a full extra 20%
The % are applied at two different stages
1 during the Purchase of Credits, and the Other during the use of Credits.
If you want to know what the total discount from the normal card is
Take the $ price and convert it to credits based on 1 credit = $0.1
so $1.1458 / 0.1 = 11.4583 credits.
then divide the credit price you pay by the Regular Price and subtract that from 1.
it's 1- (11.4583 / 25 ) = 54.16666 % total discount of the Normal 25 credit price, but only while you still have some of the 600 credits you got at the 20% off.
combined, a triple diamond gets a total 54.1666% discount,
when they use the 500 Credits Purchase with an additional 20%
i think it is easier to just say that each credit spent cost $0.08333
or 8.3 cents per credit.
13.75 credits x $0.08333 = $1.15 rounded up to the nearest penny
and that rounds to a 54% discount.
