You will find out that you are dealing with an Italian firm.

It could be made so we users could buy packs of 1, 2, 5, 10, 25, 50 and 100 credits.

BUT it is made so that the smallest amount of credits is 25. next is 45.

So if you want an object that costs 12 credits you have to buy another optional object that costs 12 or 13 credits. It must be done within a year, or your credits will simply be taken. They will be gone.

If you need an object that costs 18 credits then you will have to buy an additional credit pack. And again - what you have not used from within a year from the buy - will be gone.

In your case where you need objects for 30 credits you have to buy a credit pack of 45 or 2 x 25 credit packs.

So - you will end up with your account being on 15 credits or 20 credits. You have to decide what amount you will need for an additional object within a year. If you don't want additional new objects you will lose at least 15 credits which is about 15 dollars or euros.

Another way to look at it is:

You buy 2 objects for 45 dollars. If the objects is worth 45 dollars for you - then be happy with that.

Hi there, 

credits only come in the 25, 45 and 85 packs, it isn't unfortunately possible to purchase a different amount, I am sorry about that!

I am available for any further clarification. Kind regards.

Merhaba,

krediler yalnızca 25, 45 ve 85'lik paketlerde gelir, farklı bir miktar satın almak ne yazık ki mümkün değil, bunun için üzgünüm!

Daha fazla açıklama için hazırım. Saygılarımla.
