I found some decent sand while looking to add more sand to my reef. This is the CaribSea Seafloor Grade Special version, which is decent imo.
Petsmart has 30% off for its "online only" items. For $24.49 and 40lb, you cant beat that. Shipping is free if you have $49 or more, so add a filler item or just order 3 bags if you need that many.
