Like the title says, I need to learn how to add items on shopping sites such as Nike and shopify sites before the item goes live or after its live. Not really sure how to describe it. But I see people doing it all the time. Products are selling out before they go live on sites and I need to learn how to do it. Please help me out.i need to add sneakers to cart before it goes live,once it's live all I have to do is checkout.i know it's possible because people are doing it.im willing to compensate.please let me know if you can do this asap! Thank you!
