get multi offers via Amazon Advertising Api

does somebody have me a hint, how i can get more than the best offer via the Amazon Advertising API? I get the offer data via the API, e.g. like here: http://ift.tt/1uAg2k8

This works, but if i have the best offer for this product, it returns me my own offer. I have to get the best 10 Offers with dealerName from amazon.

The only way to get this at the moment is to scrape the amazonpage, and i dont want to scrape > 1000 products every hour....

thanks in advance
