I would like to use "Zazzle Store Builder" on WordPress: http://www.zazzle.com/sell/developers/zazzlestorebuilder. For example like: http://heartlocked.net/gifts/baby-shower/envelopes/
I can't do it on my http://clareville.wordpress.com site. Can I do it if I upgrade to clareville.com? Or do I need to do more?
The blog I need help with is clareville.wordpress.com.
