I recently I had to pull the price for a product collection and I noticed that the collection price from the API is not the actual price of the product bundle on the site. I appears that the API just adds up the prices in the CollectionProducts node, but does not account for the quantity of each (some products have multiple quantity). Is there a way to either add up the price accounting for quantity or to add quantity to each Product node within CollectionProducts? Here is the product: http://www.kmart.com/shc/s/p_10151_10104_028CO47121101B Here is a sample API call (key removed) http://api.developer.sears.com/v1/productdetails?apikey=XXX&store=Kmart&catalogId=10104&partNumber=028CO47121101B Thanks!
