I've had the WP Shopping Pages plugin for quite awhile now and absolutely love it.
I use it to auto-post products — mostly romantic movie DVD's from Amazon — to my dating blog on a regular basis.
Actually, the WP Shopping Pages plugin has been a real blessing.
I haven't been that keen to write about dating for awhile now, yet with the auto-posts my subscribers still receive updates through my Aweber blog broadcasts on a regular basis and therefore keep returning to visit the site. By result, my Google Analytics stats show no real decline in traffic despite the fact that I've done very little work on the site for months.
There are a couple of issues with the plugin that I've noticed just recently, however.
