I am not sure why this is getting much attention. Walmart is selective about which merchants they will take and Shopify is estimating only 1.200 will be onboarded by years end. Shopify claims to have 500,000 stores so this penetration is so minuscule its really not worth mentioning. In the same vein, this was all already possible using a couple of third-party Shopify Apps and merchants have already been doing this for years. All I see is PR being created to drive stock price?
