I would like to implement free shipping for orders over a set value, e.g. shipping becomes free when the customer adds £100 or more to the shopping card. This is all straight forward and I don’t require help setting it up
However…
Is there a way to restrict the use of vouchers for customers that are getting free shipping?
OR
Is it possible to allow the customer to pick whether they want free shipping or use a voucher?
Shipping and discount codes are an unfortunate pain point. This is because a customer enters their shipping address first, and then the option to add a coupon code is the page after this. With your current configuration, a customer will still be able to use a coupon code after qualifying for free shipping.
Something that may be a decent workaround is creating two coupons: one for free shipping, and another for a discount on the order (the coupon you already have). Because you can’t stack coupon codes with Shopify, this leaves your customers the option of either getting free shipping over £100 or using your current discount code.
