Depends on your range of purchase sizes and industry expectations. My product will sell regularly in quantities from 1 to 10,000, and my shipping costs on those vary from about $5 to $50, so I'd have to have a lot of price tiers. That's kind of absurdly broad, though. I'd think fabric and other categories should have a few orders of magnitude less, but I might be surprised.

But, you can do that if it doesn't fly too much in the face of customer expectation. In some industries, like printing, it's common. In fabric I think there's a strong expectation of a single price per length unit, though I suppose you could challenge it.

I don't think lots of price tiers is a good customer experience, so I decided against it as a long-term customer satisfaction strategy. I do wonder if it's costing me sales. Maybe I should set up an alternate brand that does tiered pricing and free shipping.
