I have sort of hit a snag with the Ejunkie/SwiftCD integration. My issue is suppose I charge two different shipping rates, one for US and one for international. Then suppose somebody buys my CD from Canada but on the E-junkie cart they say they are from New York. Then when they go to PayPal to pay (or Google Checkout), they type in their real address. Now maybe I can avoid this problem by including shipping in the price for all potential customers (i.e., a flat price for everyone), but there is still the problem of sales tax. A person could type one location on the E-junkie cart to avoid sales tax and then type their real address when they finalize their purchase. Any suggestions?
