A tiny bundle savings calculator (client-side, snapshot-based)

If you sell a bundle alongside individual products, buyers end up doing the same mental math: do the items I want add up to more than the bundle? I made a small calculator that does that comparison in the browser.

What it does

• Lists the products in the AEFRI Everything Bundle (17 items) with their listed separate prices (snapshot).
• Lets you tick the products you want and shows the selected total vs the bundle price ($29).
• Runs entirely in the browser — no uploads, no account, no network calls. It’s arithmetic over an embedded snapshot, so you should check the current product pages for up-to-date prices and availability.

It doesn’t create a purchase or change anything on the storefront; it’s just a quick way to compare totals.

AI disclosure

I used AI assistance (an AI coding agent) to write this post and to help build the tool. The calculator performs simple addition/subtraction on an embedded price snapshot; verify current prices on the linked product pages.
