Single price grid component

like you said, it's not perfect yet, my suggestions to you

Design

• Have a look at the colors in the style_guide.md from the starter files, the ones you use, feel a bit darker on screen
• the 2 sections at the bottom are not equally wide in your solution

HTML

• you're missing a landmark
• you're missing an <h1>, remember headings should be in order and never skip a level

CSS

• there's a lot being done with px values, try to replace them with em or rem for better accessibility
• I feel you have some rules duplicated in your code. Didn't find a particular example, but I saw it passing by
