Is there anyway to do this with a stock setup of Shopify OR a plugin?
The one that leaps to mind is Bold Apps' Quantity Breaks: https://apps.shopify.com/quantity-breaks
That should do what you're looking for. :)
The Product Bundle could be an option too:
Hope that helps.,
Any alternative to the Bold App? I tried Bold Bundle App but need something better.
Shopify - the ability to bundle products would be an advantage for most store owners I think. Is there anything in the pipeline from you?
