Make the purchase of the avatar using a trick that the page has, you will see when making the purchase in the buy button now there is a meta data in the button when inspecting the element a value appears that says: data-product and place the value of the avatar that is on the page, in this case "If4lJ" that allows sending the product information therefore sending the product that I want to buy which is Selina instead of the product on the page that I am viewing and that allowed me to buy Selina out of stock
