Pros
Great flexibility, as an artist it was great to have a platform to sell my creations on without having anyone infringing on what I should make. Etsy makes it easy to list, upload and advertise all your products from your phone or laptop, and you can update your listings anytime before or after posting them. You pay per listing which is very nice since you only have to pay for however many products you have instead of some kind of bundled cost. Ads were great, you could choose how much money you wanted to spend per day, and cancel the ad campaign at anytime. You can add as many products to be advertised as you like, and can remove them at any time. Ads showed up on the Etsy website only.
Cons
As time progressed the fees increased. Etsy takes a percent of every item you sell.
