Would you like to be able to have your online store on Facebook? Then by using a widget from Alvenda.com it can be done. Alvenda developed a widget which allows you to place that widget into your Facebook account, blog or anywhere else. Alvenda is basically an advertising network which allows advertisers (merchants) to advertise their store and publishers to promote the store via their blogs etc.
Another similar advertising network I came across using widgets to display products in your store, is from NextWidget.com.
NOTE: I was trying to use the 1-800-Flowers.com store on Facebook, but didn’t manage to as it requires Adobe Flash 10 plugin to run, but for some reason after the installation the store still wasn’t functioning. So make sure your store widget is functioning because what’s the point of having it otherwise?
I found these widgets for ecommerce stores interesting but only time will show if there is any real value in using them. But in the meantime, there is nothing stopping you from trying them and seeing for yourself.
