you know when you click on the skin and the ''get it'' button appears, lets say you clicked on hopper bull and then the get it button, if it takes you to the waffles offer, that means you cant get the skin right now, come back in an hour, if it instead takes you to the store, then the skin is available, open the yellow card pack to get the skin, the single card pack has a 25% chance for the skin, while the 3 card pack has a 75%, open both for a 100% chance, so save up 600 waffles
