Here is a test page that displays 2 single product Etsy Seller widget ads in the same page.
This was accomplished by putting the widgets inside HTML iframes.
If you have 2 or more Etsy shops, using the iframes version of the widget will allow you to display multiple widgets in the same page. It also allows you to put the widget inside a post just like I did here.

*Note:
You have to be editing your post in HTML mode in order to use this widget in a blog post.

Features:

• Automatically updates you listings every 15 minutes
• Mouse-over the image to pause scrolling
• Click on » and « to move to the next and previous item respectively.
• Click the Buy link to add the item to Etsy’s shopping cart
• Click on More info to view item in Etsy
• Written in Javascript (jQuery)

1. Go to http://Cr8tivity.com
2. Type in your Etsy User Name or User ID
3. Click on the “hearts” button
4. In the Hearts page, click on the “Widgets” tab
5. In the widgets page, click on the 1 Product, 2 product or 3 product link
6. Copy the HTML code that is given for your shop
7. Create a new HTML/Javascript (In Blogger/Blogspot) and paste the HTML code then save.

Today we are releasing 2 new flavors of our popular Etsy seller widgets. Most of you have seen our single product Etsy seller widget. This widget scrolls through all your current Etsy listings. A nice thing about this widget is that you do not have to create a new one every time you add a new listing. It automatically adds your new listings.
