There is no issue or bug at all with the packs you get from Scratchcard, but you will get what is written inside the card instructions.
Example: If it was written "when you use it, you will receive randomly packs .... The maximum value of the package is $99.99", meaning you can get this value $99.99 or $49.99 or $19.99 $9.99 Or $4.99 or $0.99, depending on your luck, so we wish you good luck.
