one store two locations

Hi,

Well, you could just create a custom field of the table "order" via the menu Display>Views, to let the user select between the two stores and move the "fields" view in the first step of the checkout workflow in the HikaShop configuration.
But what it means for you to allow the customer to choose between the two stores ? Does it changes something for the price ? For the stock ? For the email notifications ? For available shipping methods ? Based on what you're trying to do, it could change my answer completely.

Hi,

You're almost there. In your last screenshot, in the "new view" area, you need to select "fields". Then, select the field you created in that new view and move it where you want it in your checkout workflow and you'll be done.
