How can I enhance my online store's performance?

Hi,

could you check out my store and do a brief or detailed summary of what is bad or what could change. Please recommend other websites that are great, or apps that I could use. This is an overall question in both design, conversion optimization and everything else.

Please help!

My website: www.cardtag.net

Thanks in advance!

Hi,
The discount is applied automatically for all shipping within europe. Thank
you for replying, and what is with the design, and marketing or more you
would like to help me on and discuss with me?

I would be pleased to hear your opinion.

Best regards
