Have you ever thought of using FBA?

You can opt-in their Prime program and offer free 2-days shipping to your customers.

I think there was FBA integration in Shopify but they're dropping it, but an app still let you integrate with FBA.

Yeah, I tried to push for that. The margin on the products was too small. Due to some nasty wording in franchise agreements, the actual markup was 25% at most, terrible rates for retail. There just wasn't enough room to play with discounts/promotions as well as external servicing. At least not at their low volumes. I've seen other FBA projects go quite well though.
