OK this is a real deal!
If you own a blog with a decent Page Rank, and quite a few hits visit this web site La Compagnia del Cavatappi® (the corkscrew company) and freely write a review about the site (is it usable? are the products worthwile?) using in your links the keywords they suggest for their products, and you’ll get a 25 € (including shipment) voucher to spend on their site on wine or italian food.
Remember once you have posted your review on your blog contact them to let them know you wrote about them.
Unfortunately the blog La comapgnia dei blogger where they say all this is only in italian.
Enjoy!
