+### Costs
+
+This project is hosted on Vercel, and uses many of the features of the Vercel platform.
+
+Here is the full breakdown of the cost of running this project from Oct 20th 2024 through Nov 11th 2024.
+
+During that time, the project recieved **over 1 million page views** across 45k unique users. The site has **over 1 million unique pages and images\***.
+
+\*_images are unique by url (and caching) although not unqiue in their content_
+
+#### Summary:
+
+- ~1 million page views
+- ~1 million unqiue product pages
+- 45k unique users
+- $513.12
+
+Is $500 a lot for hosting this site? It depends, in this instance if it was a real ecommerce site that hosting cost would've been made back in the first 10k visitors.
+
+It is likely possible to optimize these costs further if that is your goal, however that wasn't a priority for this project. We wanted to try and build the fastest possible site, quickly. We definitely achieved that goal without ever having to think about infra once.
+
+These numbers are also on top of the Vercel pro plan, which is $20/contributor/month.
+
+We would like to thank Vercel for covering the costs of hosting this project.
+
+#### Compute and Caching
+
+These costs represent the core functionality of serving the site.

+
+Total: $353.12
+
+#### Images
+
+These costs represent the image optimization done by Vercel.
+
+| Resource           | Included    | On-demand | Charge  | Notes                                                                                                                                                                                                                                                                              |
+| ------------------ | ----------- | --------- | ------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| Image Optimization | 5000 / 5000 | +101,784  | $160.00 | This represents the number of distinct source images used on the site and optimized by Vercel. Each of the 1 million products has a unique image. The reason this number is less than 1 million is because the optimization is done on demand and not all pages have been visited. |
+
+Total: $160.00
