Are you an ambassador/affiliate with a brand? What's the difference?

I see people talk about products purchased from a few sites -- YesStyle, StyleKorean, Stylevana, and others. So I was curious on how many of you are Ambassadors/Affiliates for these types of companies. I am with quite a few myself. The three listed above and more. But really, do you know the difference? The biggest difference is $$. Both how you are paid & what you get in return. Affiliate -- is a person who markets the brand in return for a commission. Commission can also increase in % the more people who buy products under your links. You don't make any money unless items are bought. Typically, you have a specific link you use, or tack onto the end of a product page. It's how the company tracks sales. Often times, you pay for your products. Ambassador -- is a person who promotes a brand, but may not get paid in a traditional sense. Sometimes you get a fixed fee per post of the brand's products, a free product, gifts, access to new items, secret sales, etc. Yes, some ambassador programs offer free products & track sales for commission. Both can set terms and deadlines. You may be charged shipping fees depending on where the company is located. Either way, the choice is obviously yours. I do advise doing your homework before accepting. Take for instance StyleKorean. I get 3 products from a specified list for $9.99. However when you add in cost of shipping, it comes to $29.99. If you do not finish your reviews in time, they can ban you from the program and/or charge you full price. There are many out there that are scams. I am sure if you are on IG, you have gotten the messages "free products all you have to pay is shipping". It's normally outrageous shipping costs too. I've done a couple in the past just to see. The most I was charged was $65 for overseas shipping fees. The products were extremely cheap looking & most were broken upon arrival.
