If you want multiple copies of Dissolving Dollars, you can get them for $9.99 each if you order them from this link; once the books are in your shopping cart, enter this discount code DSC53EL8 (there will be a place for it). Since Amazon offers free shipping for orders over $25, the $9.99 deal is only worth it if you are ordering several copies because there will be a $6 or so shipping fee depending on where you live.

If you want over 10 books, contact me for even better discounts.
