The current online ordering system is a little klunky. It showed double shipping charges for my auto-ship items. However, Jennifer watched my account and made sure that the shipping fee was only charged once. I appreciate her excellent customer service!

Prior to recently, these products have been on my top 10 list; however, since the prices have risen and continue to rise, I am not sure if I can continue to use these products. This is very disappointing to me as I really like these products.

I really like your products. However, with so much competition, I would conmsider free shipping, as that deterred me form ordering this time

Love their products and excellent shipping. I receive my order within days, it's always well packed . I order product for my autistic brother also, and his order comes in quickly. The only problem I had was when I placed a big order when all products were on sale but they were out of max energy Bs. It was back in stock a few days later. I called to see if they would ship it for free, but they wouldn't. Other than that, nothing major.

I rate the products and the customer service from QNL a solid five stars. The only reason I am rating the company four stars at this time is because they recently changed the way that quantity discounts are calculated. Specifically, in order to routinely get the best quantity discount, customers now need to order nine bottles of a product. Therefore, it behooves customers to save money by trying to schedule their buying around holiday sales and the annual July sale - and we remain extremely grateful for these product sales-but it is now more of a challenge for the customers to get the best value for their money.

On my low income I’m reduced to just being able to buy one, but I’m happy with that one supplements performance. I wish the shipping wasn’t so expensive. Since I can only afford to buy the one supplement at this time, I am paying 9.95 for one bottle to be shipped within the same part of my state.

I have come to trust the efficacy and the quality of your components in your supplements, having been a customer for over a decade, but I’m always a little bit uncomfortable with your pricing. It seems excessive. I think it’s weird that you don’t fill up a bottle of capsules, but charge a high price for only 60 capsules, which don’t last more than 30 days if the recommended dosage is “take two per day.” Even worse, if the dosage is three per day, then the supply in the small bottle only lasts 20 days; for example, one product called CircuZyme. I understand the superior quality of your products, at least I trust what you claim, and that’s probably why you justify your high prices. I wish you would provide more discounts and special deals more often, to your loyal customer base.

I was very happy with the QNL supplement, and have used for years. My one complaint has to do with changing to the subscription plan. The billing site is not user friendly which resulted in confusion with shipping orders. I am appreciative that my refund was promptly processed.
