eBay's Value Positioning: eBay captures price-conscious consumers and refurbished product buyers, typically at 15-20% lower price points than Amazon. The platform performs well for sellers offering competitive pricing.

Shopify Direct-to-Consumer Advantage: D2C brands on Shopify command premium pricing (25-40% higher) due to direct customer relationships and brand control, though at lower volumes.
