Hello!
i’m trying to set up variant for my Custom T-shirt store.

Let say that my customer want to buy different shirt with different sizes in the same simple order. How I can set up the variant.
Let say that I have an offer that include 100 T-shirt in bulk offer.
how the customer can pick different amount per size?

Hi @LivingTruthBrad ,
This is Theodore from PageFly - Shopify Page Builder App.

To offer different sizes of t-shirts in your online store, you have to make the product and specify the sizes like small, medium, large, etc. If you want to sell 100 T-shirts together, make it a separate product or option. Use special Shopify tools like “Bold Quantity Breaks” or “Infinite Options” to let customers choose how many of each product size they want to buy. You might have to change the product page to make it clear and keep track of the items in stock. If the setup is hard, it can be helpful to talk to a Shopify expert or developer. Make sure to test the process so it’s easy for users and updates the inventory correctly.

I’ll be so happy if my suggestion can help to solve your problem. If you have any further questions, please feel free to tell me.
Best regards,
