Affiliate Marketing Secrets

Please help me. l have a website and my hosting is running out because am not using it.
Basically, l like to sell different product on my website “like kids toys, digital item, etc..” but l don’t have money now to purchase those item now. So am guessing is there a way l can find a store or website that sell all the item then add it to my website and purchase it for cheaper price then send it to customer.
Does any body think this a good idea?
Or
If there is any manufacturer out there that can permit to me add there product to my website then purchase it from them and earn commission.
The so called affiliate is not working for me. Any advice please, Thanks in advance.
