Checkout Blocks & Customizer vs PrettyDamnQuick (PDQ)for Shopify (2026)
Checkout Blocks & Customizer and PrettyDamnQuick (PDQ) both operate within the "Checkout - Other" category on Shopify, aiming to enhance the checkout experience. However, they appear to approach this goal from significantly different angles. Checkout Blocks & Customizer, while boasting a perfect rating, has a very small sample size of reviews (5), making its long-term reliability difficult to gauge.
