Pixel Scrapper is one of the first digital scrap booking sites I discovered and I love it. You can download papers and elements individually - only what you want - for free! What's more is that the community is full of helpful, kind, and welcoming members.
The site runs on donations and this month they started a subscription plan. You get unlimited personal use downloads for just $5 a month (regularly $10) OR unlimited commercial use downloads for $10 a month (regularly $20).
Consider signing up - I know I am!
