gin is when you set the most credits you would want for this auction,lets say you wanted 8500 credits for this gift card,and some1 really wanted it but didnt want to wait the 10days out,well they would click on your gin and that would end your auction,and winner get card and you get 8000 credits,cause lista gets a percentage,i forget how much but you get your 50 credits back,after its over plus the 8000 you wanted,but you cant get gin until you sold 5 items i think ,im not as new as you,but im learning still,but when you do a gin,you can figure out what you would like to sell it for in credits,and you can figure out how much lista will get if its use,so,you just put it up higher,so you get what you like on your auction,hope this help a bit,fan and watching!! and welcome to lista
