In exchange for an initial donation we will give a card that could be used to purchase goods from us.
The card will give right to some discount on anything that will be bought using that card.
The amount of the discount will change depending by the amount of the donation.
Of course it could also be used as a gift card. At the end of the year, if the owner of the card hasn't found anything worth buying, we will refund the amount of the card completely.
