Hello, Shopify Community.
I am a new one here and looking for your help
I am in need of a Shopify app that can create complex coupons and cart price rules. Specifically, I require a solution that allows for a coupon offering a 25% discount on an order, along with an automatically added free gift when certain specific products are purchased.
Could you please assist me in finding such an app or provide guidance on how to implement these features?
Thank you for your help 
Hi @Vo_va
i recommend my app B2B sollution
App used to adjust product prices based on product type and customer target, for websites selling to B2B/wholesale customers. For example, the host store can determine priority for wholesale customers who have registered accounts. Customers who are not logged in will see a different price.
