Sam's vs. Costco vs. Walmart
For several items I make, I just need a standard AP flour, brown sugar, salt, etc....and I've been buying multiple boxes and bags at Walmart for a while but as I look to increase production and actually sell at farmer's markets...I'm wondering if I need to invest in a bulk store account?
My concern is that Walmart (or really, any grocery) tends to randomly and suddenly run bone-dry on some baking items.
Has anyone used Sam's or Costco? Is it worth it?
Any other options I'm not considering?
