I'm just starting out but after extensive research, it makes sense to order a sample. If done, then put down a small order and get delivered to yourself for QA. I've seen Some manufacturers saying they will ship to an Amazon FBA centre so worth looking into considering all shipping costs, tax duty etc. Otherwise have it delivered and do yourself to start off. Start small, get use to the whole process and negotiate with manufacturers on MOQ, price etc.. Most are willing to listen.
