I needed something dead simple and mobile-friendly to easily see my Topps Heritage needs. I would love to at least wrap up the refractor needs (
I've been asking for awhile...)
Take a look:
https://inv.us175.com/wantlist-heritage/
I took an export from my actual inventory site and generated some static pages. There's no live update functionality like there is with my inventory site, but this is guaranteed work even with poor internet.
My typical wantlist page is
https://inv.us175.com/wantlist and has pictures and contact info. It's meant to be shared online.
If you're dying for something like the bare-bones page, I can help you out if you send me a spreadsheet sometime today.
