I paid € 2 / booster (approximately $ 2,70, 5 boosters total, so it's no financial disaster but it's just dissapointing to buy something and find out it's fake) which btw leads me to the conclusion that especially cheap boosters are doubtful since you can't see what's inside without opening it. Indeed there is a difference in the fonts but it's (at least for me with these particular packs) far more difficult to spot them as fakes than single cards which you can check on all sides ...
