I've never ordered wine online (until recently, shipping out of province was a no-no, correct?), but if I have a choice between a credit card and a bitcoin, and if I trust the seller, bitcoin wins because of ease of use, simplicity, and speed. It's a no-brainer.
The test Website has annoying coinurl advertisements in the footer, please get rid of that. It's a wine selling business, not an ad-supported blog! I just saw a banner for feathercoin come up. A perfect way to confuse curious visitors.
