I feel that Costco really gets their products. The Kirkland stuff if on par with the top band brands. Their return policy is superb and the pricing is excellent. I just wish they gad free return shipp.
I do the annual subscription and have been for about 2 years. I live to get a surprise package every month! I especially enjoy getting the add ons. Every month they offer a few products for $12 or $ 18 that are usually so much more at Sephora or ultra. I have found their customer service helpful and quick to respond when I have an issue with a broken or missing product.
I have been getting my FabFitFun boxes for over 2 years. It's about $50 a box and the stuff in to box is usually worth a lot more. It is super fun to get a box a few times a year. Some stuff I use, some I pass on or gift.
Tip for consumers: Do the annual subscription so you can choose products
