I have purchased items from QNL for the past 5 or more years and have always been pleased; however, I have noticed a decrease in availability of items and service in the past 2 years. I hope this improves because I've come to depend on QNL. I'm not too pleased with the 'fermented' items....they seem to spoil quickly. I would have given this 5 stars except for the last couple of times I have tried to purchase some items and they are not available (e.g., gallbladder PG, heart PG, limonene, et al.) I wish more would be more readily available on Amazon. I miss Bob Marshall.
