The best thing about NFS is that it has an excellent support system with their live chat feature which makes contacting them very easy! I have had to contact them many times in regards to issues or questions regarding our account but they are always quick at responding and extremely helpful when solving problems. They also offer free shipping (which we use often) as well so there's no need to worry if you don't want your items shipped through USPS due to cost concerns. We've been using this program since 2012 and haven't found anything bad yet - everything works flawlessly! If anyone asks me what my favorite part of this website/service is I would say without hesitation "the ease of ordering products via Amazon". It saves us time because all orders go directly from Amazon to NFS rather than having to place multiple orders separately. This allows us more control over how much inventory we hold versus relying solely upon stock levels provided by other companies like Target and Walmart. Also helps keep track of sales.
