I work at Hancock's & we can take a fabric coupon for "by the yard" interfacing...& a notions coupon for packaged interfacing. Hancock's doesn't consider batting a fabric though.
As for special orders, if it's a fabric that we stock in the store...no shipping charge. It's called a warehouse order. But if it's a home dec fabric ordered from our swatches, then it's a dropship order & there is a shipping charge...& it's delivered to the store (not your home), too.
