What customers say about Google Merchant Shopping Feeds OC 3.x
I found this extension useful at first but after Google started requiring "availability date" for all pre-order and backorder products the developers were not providing the support and updates I paid for. They refused to refund me despite the extension not working for such products.
works amazingly , lot of options to filter products in merchant center,with product type , custom labels and the bulk upload feature make is so effective tool and must have for google addwords. thanks
