Find the theme you want to edit and click Customize.
Open the drop-down menu at the top of the page.
Select Products, then pick the product template you want to edit.
In the side panel, click + Add block or + Add section where you want the button to appear.
Under the Apps section, click Make an Offer Button to add the block.
Click Save to activate it.
For Legacy Version (V1):
If you’re using the older version, you can change where the Make an Offer button appears by editing your theme code:
In Shopify admin, under “Sales Channels,” click Online Store and then Themes.
Click the … button next to your theme and choose Edit code.
In the “Search files” box, search for products.liquid and open the file.
Find this code:
<span id="mf_button"></span>Cut (not copy) that code, and paste it wherever you want the button to show up.
