Creative Market and YWFT are online marketplaces for design content from independent creators. On both websites you can buy digital goods for your personal and commercial projects, without having to purchase a subscription plan.
I sell vector graphics through various microstock sites. If you are a designer who needs digital content on a daily basis, you probably already know these, so just pick your favourite:
At Redbubble you can buy a lot of different products with my artwork on them: framed prints, laptop covers, stickers, tote bags etc. Unfortunately my Redbubble profile is rarely up to date - if you'd like to buy a product with a certain image and it's not there, please let me know.
Unfortunately, I am currently not available for custom requests. I apologize for the inconvenience.
