A while back I looked into creating a shopping cart for the store.
I did not get very far, but finally had some time to sit down with Grok to prod me through it.
With many errors following trials Grok pushed me through the process.
Grok was pretty impressive giving me starting points and analyzing errors.
This version uses a lot of inline code, so kind of clunky to setup. I did try to get Grok to help with a plugin version, though it got stuck at one point, though if need be I could disable that feature.
Still have some funky colors to fix.
