How do you get free coins on ninja kiwi

But with no download...! I believe there's only one way, and that way is to have a glitch happen like say you have 10 ninja kiwi coins by getting some with the wheel of fate. then you add to of then to cart that cost 10 ninja kiwi coins each and then checkout and the next day you might get some if it says -10 or mines 10 ninja kiwi coins where it says your coins well NOW the next day after you done that again you should get allot of coins because that's what happened to me and i came up with... about... 2,02020 i think that's how much i had on my memory and my memory's good but usually i get on memory 1 or 2 numbers wrongs maybe you only get 2,020 instead.
