umm.. Prime is 2-day delivery. I ordered something Saturday night via Prime and it's scheduled for delivery Monday. We placed 70 orders on Amazon last year and 90% were Prime meaning 2-day delivery. Not 2 business days, 2 days. We have received deliveries on Sunday. So I'm not sure about Prime shipping being "far slower", maybe you meant non-Prime? btw Prime includes free returns and I've never had an issue returning something. A couple of times Amazon sent UPS to our door to pick up a return.
