The idea is to look at the offers from a different point of view and different currencies. Most of the time, both values are close to each other, but there are subtle differences.

In order to surface more information within search results, I’ll be tweaking my posts. The first valuation which is in USD is based off the calculations by @Sir_Crapsalot. Please check this post for details. In addition, I’ll adding a footnote linking to valuations in other currencies whenever available - e.g. SGD by @BlackZed
Synopsis A fair value offer as you get dollar for dollar in game value.
25x Costume Key
Synopsis A plus value offer as you get more game value dollar per real dollar.
50x Costume Key
Synopsis A plus value offer if you consider the food/ham, otherwise a fair value offer. However, if the trend holds, we should also see the Feel The Might (Eloise) on Day 3 which is arguably the best offer for buying costume keys (no gem/item tax) - you pay $1 per pull which is the cheapest costume pull.
