Simprosys Google Shopping Feed

We have more than 40k products and tried almost each and every app in the app store. So far this is best in terms of performance. Other than that, some of the features of this app like filtering and bulk edit, ability to edit the product titles, promotions feed for specific products, etc... are nowhere else. Above all, support, you must talk to Amit if you have any issue. He is go to man for your any query or error related to Product Data and Adwords.
