Breaking down the numbers:
3 1320 credit packs = 1122 tickets
"fun and games" = 1699 credits used = 910 tickets
Cards obtained
- 5 standard
- 50 crystal clear
- 35 crystal clear +
- 3 gift cards
- 2 jokers (I used 1 up for the tickets)
- 1 SEC card
- 1 Ex card
Assume I bought these cards through the store, then
5*12 + 50 * 18 + 35 *18 = 1590 credits (as a double diamond user)
Then the cost of 3 gift cards, 2 jokers, 1 SEC card and 1 EX card would be:
1699 - 1590 = 109 credits
The numbers are for your reference, take it as you see fit.
