Hello,
I recommend you do drop shipping. You find a supplier, list their items and once customers BUY the items from you, you go to the supplier and have him ship the items directly to the customers.
This way you never risk any funds up front.
Whatever you do, don't spend money holding stock, unless its a VERY popular item that you KNOW will sell very well.
Feel free to chat for more advise if you wish.
Best Regards,
Andrew.
