Drop Shipping Vs Affiliate Marketing !

Good Day Guys !
Which is better Drop shipping or Affiliate Marketing?
Drop Shipping
- Dropshipping is a way to run an online store where you don’t have to store inventory or ship product. The way it works is that you set up your storefront and collect money just like a regular store. But instead of having to pack and ship the product once you receive an order, you simply place an identical order with the distributor at a wholesale price and the distributor takes care of shipping the product to the end customer for you.
Affiliate Marketing
- Affiliate marketing is when you refer a customer to another business and take a commission if the customer makes a purchase. In effect, your website acts like a marketing and referral engine and you don’t actually sell any product. In addition, you don’t directly collect any money either. Once a sale has been made, the affiliate business is responsible for paying you your commission which usually occurs on a monthly basis.
