I don't buy much in the way of cosmetics or hair products in the drug stores because I find their mark up ridiculous, as ridiculous as the mark up in department stores.
I do most of my shopping for high quality beauty and hair products on ebay and usually save 50-70% buying them there... my Pureology shampoo and conditioner will cost me $90 for two 33oz bottles which will last for at least 10months (
that amounts to less than $10/mo on shampoo and conditioner).
Buying on ebay isn't convenient for a quick, easy fix - it requires patience and searching out the best deals but I've found it saves me a ton of money while still allowing me the indulgence of high-end products.
Similarly the Redken volumizing hair products I would pay $15-20 for in the salon or the drugstore, I can get for $10 or less on ebay...
YSL Touche Eclat, the best highlighter pen on the market costs over $40 in the department store, but I can find for $12-16 on ebay...
Urban Decay palettes that run $50+ I can find for $25, on average....
Benefit lipsticks cost $22 per tube, I can find them on ebay for $10 or less...
And if I do enough deal searching, I can buy most of these products with no shipping charges.
One drugstore item I LOVE is: Witch hazel, an all-natural astringent/toner. A bottle of Clinique's toner/clarifying lotion costs $35 or more, and contains mostly witch hazel.
Thayers all natural remedies witch hazel costs $8 and IMO works better, and it can be found in most drug stores, grocery stores or places like walmart/target.
Oooh and Loreal does a wonderful line of eyeshadows called "HIP" High Intensity Pigments. I prefer the loose eyeshadow called "
HIP Shocking Shadow Pigments" that comes in a small pot. This is "going out/dressing up" eyeshadow it has an intense bold concentration of colour. I love the two shades I have. I've found it on ebay and amazon for about $5, I think that is about half of what I've paid in a drug store. *great product and lasts forever!!!
