I just wanted to say THANK YOU for four years of first class service. I'm absolutely thrilled to do business with your company. I have never had an order that wasn't perfectly fulfilled and on-time. There are not many companies that I can say that about! In a world where we expect online shopping to be perfect, but seldom express our appreciation when it is, I just wanted to reach out and thank you. Dawn, Maine

So pleased with my 1st purchase. The products taste great & have the nutrition I was looking for to keep me on reach for my New Years goals. The way it was packed & notification of delivery were both top notch. I will be back again soon & recommend it for friends. Thank you! Jenn, Nebraska

I cannot say enough about your company. The products I've order and service are over the top. Mary, Florida

IMPRESSIVE! I am overly joyed as a new customer. #1. I ENJOY my products. #2. I am overjoyed to find products that are BETTER than, CHEAPER than, and more NUTRITIOUS than my diet program foods. #3 I LOVE the fact the products are labeled MADE IN THE USA and #4 the SHIPPING was IMPECCABLE. Oh yeah and the SAMPLES are perfect, Thank You. I will be ordering for many years to come. A Very Happy Camper. Nicole, Maryland

Just need to tell you how AMAZING your company is!!! I was aware of your Holiday Shipping Schedule and was not expecting my order to ship out until Monday!! I was quite surprised (actually, not really as you have always been fabulous) to have received tracking info on Friday, and received my order TODAY!! That means that someone went into work on their supposed day off.....packed my order.....and shipped it out....THE SAME DAY I PLACED THE ORDER!! Now THAT'S DEDICATION!!! You truly are AMAZING!! Beverly, Massachusetts

I must tell you that I am so impressed with your company and how each representative that I've had the pleasure of speaking with has gone above and beyond to make my experience beyond fantastic. I live in Brazil part time, so when I am back home in the states and place my orders, they are usually rather large and complicated... But every time you all have been so helpful and thoughtful and I just want you to know how much I appreciate it! My mom and sister are also devoted clients and we honestly always talk about how great you guys are! it is so nice to buy from a company who really seems to value their clients and that goes out of your way to make our shopping experience very enjoyable and easy! Court, Illinois

I have been buying products for over a year now.... couldn't be happier - fast shipping, easy ordering, great tasting products to help keep me on track with a low carb, low sugar diet plan. I have recommended to family and friends. Thanks Nashua Nutrition. Nancy, Canada

I love, love, love this site! From the simplistic way in which everything is organized when you shop, the fast shipping/customer service and delicious foods. Keep up the great work and thank you. Karen, Maryland

This is my 3rd time ordering from you and I just HAD to email you to say you guys are awesome! Fastest turnaround on any order I've ever placed for anything anywhere! Less than 24 hours from the time i order until delivery is on my doorstep! Keep up the fantastic work, you've clearly earned a customer for life. (and I tell everyone who will listen). I live in NY and its actually quicker to order from you and have it delivered then it is to have to think about what i need at the store, drive there and buy it. Nice job, just had to tell you. Melanie, New York

Just wanted to express my thanks. Your company is the best. Service is outstanding and product is wonderful. I've been able to maintain a recent weight loss by using much of your product line. Again many thanks to your staff....I'm very satisfied. Claudia, Rhode Island

I want to say how much I enjoy purchasing from your website or calling your offices. You are one of the best sites I have ever visited for customer service; prompt, courteous, professional. You should be proud of your staff, they are awesome. Syndie, Washington
