While playing a Zendikar quest, i noticed some very strange pricing between a booster pack and a fat pack (8 boosters in it) :


Is it really supposed to be like that , a fat pack price being less than 2 times the price of a booster pack ?
I checked in Vecc booster-prices.txt file and noticed there are no fat pack price defined (only booster pack and booster boxes), so i suppose the problem exist then for every sets, not just the Zendikar block.
edit : checked in other world, and it looks like fat pack all have the same price, even those old sets fat pack. this really needs fixing, it's a huge exploit to be able to afford easily a very old set fat pack while their corresponding solo booster packs are outpriced, you can then make insane amount of money when selling those cards.
edit 2 : not sure if it's me being unlucky but travelling multiple time to make shops change their items to check the prices, i have not seen a single booster box, only booster pack and fat packs
