Questionable math in Daily Deal
Today's "Daily Deal" features a New Capenna Mythic Pack for "-15% OFF", which is strange because the deals usually say something like "15% OFF" or "50% OFF", without the negative sign. This led me to wonder if perhaps the deal price is actually HIGHER than normal, so I went to check it out. The regular price for the Mythic Pack is 260 gems and the deal price is 230 gems, so it is indeed a discount, but only 11.5% rather than 15%.
Perhaps someone based the deal display on the regular (non-Mythic) pack cost of 200 gems? In that case, 230 gems would indeed be "-15% OFF".

15% of 1300 gold is 195 so the price should be 1105 Gold
The last two mythic pack deals have been listed at 1150 Gold which is 15% off of the cost of a regular pack (15% of 1000 is 150)
Pretty sure this is illegal in some places so you should probably fix that
