96% showing on SteamDB yet only 85% showing on store

[Bing Weak]

is steamDB wrong at giving discounts?

[Stormtrooper]

It's referring to the 2K Horror Bundle, which includes Bioshock 1 & 2, The Darkness 2 and The Quarry.

The Quarry was on sale for 96% for only a few hours. This was possibly a typo or something since it later changed back to 85%.
