I found this odd too. Most of the largest wholesalers have microscopically thin margins (i.e., they're not making much from you), whereas grocery stores tend to be a lot higher. I'm not an expert in the food distribution business but it seems most wholesalers (McLane, for instance, https://www.mclaneco.com/content/mclaneco/en/customer.html https://www.mclaneco.com/content/mclaneco/en/customer.html) are happy to take new customers. Maybe Sam's club is offering a better deal than wholesalers on specific items because of coupons/sales and whatnot?
