My In-Stock Floor&Decor Paint Order Taking 3 Weeks To Ship

I bought three gallons of paint on June 1st because their website said they had it in stock. Now it's almost end of June and looks like the status of the order is still "preparing for shipment." They say it's in stock, but it takes three weeks? Please! They tell me that "special orders" take 30 days. They don't talk about that anywhere on their website, and they haven't even bothered to give me a rough delivery date, no one knows what's going on. I'm making changes to two bedrooms and the living room! I have paint for one room, but because of this mess, I can't find enough for the other, do I have to drive to every store in town to see if they have enough paint because they can't ship it from one central warehouse?
