I personally got fed up with going to the store and being told that "this" was the product I needed only to find out that it was not! My medicine chest was full of overpriced cheap products that just didn't work. Same for the skin care products that the sales person would talk me into buying. (Most beauty products bought in store are impulse and feelgood purchases, sales people trained to sell you things you don't want or need.) I found that the best way to buy my health care and skin care needs was to do the research online, get products that offered a guarantee that you could actually enforce and try the product with no risk. Not to mention that the products on offer are all of the highest quality.
