I ordered a t-shirt on shopify almost 3 weeks ago and it still hasn't been shipped out. When I messaged the supplier, he said there was an issue with his orders and someone else got their order shipped before me. Im not sure how ordering and shipping works with shopify. This is the first time I have ordered anything through the site but I feel like he is giving me the run around. Why would someone's order going out before mine cause this much of a delay? I've already paid for the shirt, so it should be printed and sent shortly afterwards, shouldn't it?
