Affiliate Marketing Delivers

how can you set up affiliate marketing with more than one company?
I want to create a website and part of it selling products from other companies like amazon and bodybuilding.com, but how can i do this? They will be going to same page but have to pay for 2 different shipping charges that might be delivered at different times, and i plan to have more than 2 companies.
is there a way to make it all in one or do you need to have them ship stuff to your own warehouse for that?
As an affiliate, you’ll just have to resign yourself to the user visiting two separate websites, ordering, and receiving shipments. If you want to sell it all together, you would have to carry inventory yourself, just as you discussed.
The one exception might be if the non-Amazon company offers their goods on Amazon, which many e-commerce companies do. You could then send your users to that version of the product.
