$6.43 at both Amazon & Walmart. Walmart has free Pickup. At Amazon it’s an add on item which requires a $25 order to purchase or S&S is available to get free shipping (no S&S discount though).
Edit: there is a 5% S&S discount, but only if you have 5 items or more in your S&S monthly order. – Thanks geocacher99
I think this usually goes for $9-$10
