Niche Pro: Create a "Shop My Wishlist" Page
If you are a member of an Affiliate Program you can add a feed to your site in any widget area. If you would like to create a page, add the shop code provided by your vendor to the "text" tab (NOT the "visual" tab) within a page.
Most bloggers use ShopStyle or RewardStyle. The affiliate companies will provide the code, and give you instructions on adding it to widget areas, and within posts etc.
