I used Photobucket for free until 2013, when I started a build thread here that got very popular. When my free megabytes got used up and nobody could see my pictures until the next month, I started paying for the service so I could make updates to the thread. The price was $25/year, and it still is. It has never gone up, and they never approached me asking for more money. It's on an auto-pay arrangement, and it has never stopped working - no watermarks either. I guess I got grandfathered in.
