Real-world origin

Built at the market booth before it was a product.

Priced fairly

Small vendors shouldn't pay enterprise prices.

Shopify Apps by MAD Valley Productions

PopUp: Sell by Weight

● Available

Shopify POS doesn't support selling by weight. PopUp fixes that — and keeps everything in one place, no Square required.

  • → In person weight-based and by-item selling
  • → On-device catalog loads instantly, even with no signal at the market
  • → CSV import/export for on-device catalogs
  • → Forgot something? Add products from your phone on market day
  • → Every sale syncs to Shopify automatically — one report, one receipt

Launch Day

In Testing

The storefront lock control for your releases.

  • → Full Site Lock — lock your entire storefront until you're ready
  • → Collection Lock — locks stay smart: products added to a locked collection later are automatically locked too
  • → Product Lock — select any number of individual products to lock
  • → Hide Buy Button (our most requested feature) — hide the buy/shop button without unpublishing, at the site, collection, or product level
  • → Password access on every lock — give VIPs or newsletter subscribers early access before a drop, or keep a wholesale-only collection locked to everyone but your wholesale buyers
  • → Scheduled auto-unlock/re-lock — set it and forget it, drops open and close automatically

Planned for future releases: page locking.

Feature complete and in testing.
