How can I adjust the quantity selector increment on the Dawn theme?

Technical Q&A

Topic summary

Goal: Adjust the Shopify Dawn theme’s product quantity selector to change in steps of 25, applied only to specific collections or sections (not site‑wide), and implement tiered pricing that lowers the per‑unit price at defined quantity thresholds.

Key details:

  • Dawn is Shopify’s default theme; the quantity selector is the control that increases/decreases item quantities.
  • Required increment: +/− 25 for selected collections/sections only.
  • Volume pricing examples: 50 pieces at $1.35 each; 500 pieces at $1.20 each. The user notes a different discount when ordering over 500.
  • Storefront URL and password were shared for review: thirstyrhino.myshopify.com (password: skeipe).

Status:

  • This is an initial help request; no solutions, code, or implementation steps have been provided yet.
  • Discussion remains open with unanswered questions on how to customize the theme and configure tiered pricing for specific collections.

Hi! I was wondering if it’s possible in making the quantity selector increase and decrease by increment of 25 instead of just 1. But for specific collections or sections instead globally through the whole website. And that when you increase, for example over 500, it’ll give you a different price discount.

For ex.

Customer orders 50 pieces, so it’s priced $1.35 each per piece.

Customer orders 500 pieces, so now it’s priced $1.20 each per piece instead.

Thank you in advance!
