“Dirty Water Records is the in-house record label of London’s famous Dirty Water Club. The label, like the club, focuses on 60s-influenced Garage Rock.” [Quoted from Wikipedia] This start-up E-commerce website has been launched since mid March.
Drupal's E-commerce module has been used for this online shop. It didn't take me much time to set up the layout copied their previous website. As this is the first time I used the E-commerce module, it took me a 2 days to figure out the general usage of this module. Shipping cost is one of the most difficult tasks.
Another fun and painful bug I encountered was the mysterious extra charge after sending the visitors to the paypal checkout page. The answer is the additional charge set in the client's paypal account. It did take me a long time to find out as I don't either have the access to the client's paypal account or have a business paypal account myself. But - I am glad we worked things out in the end. :)
