The restrictions on using credit at Books on Board are even worse -- you lose all rebates if you pay with their store credit, making the books effectively list price, as they almost always run their sales by having large credit rebate, not a percentage off and then a rebate on top, as FW does.
To the poster with $10 credit - add $20 to your account and you can buy all of these books and still have $30 credit when you get done. If you did their survey, you get 25% using that coupon (good on all orders until it expires), so you'll need to add less. if you don't mind only getting the cheapest ones, you can probably get away with only adding $10 credit - not a bad deal to loan them $10 and get over $200 worth of books.
