When you mulitple origin activated, and orders come from different locations (same city) shopify double postage charge.
We have a warehouse and stores in same city. If item sold from store we get it warehouse to fulfill together. Even if we sent from separate location no business can survive or get orders if they charge double shipping. This is a huge error from shopify and has cost my business in these tough times for over a month now.
You keep saying developers will fix but you obviously do not care about small business.
