You as the buyer understand that all cosmetics are FINAL SALE. I will not take back any items unless the incorrect item has been sent to you. Prices are set at a current supplly/demand ratio. Most of the items I sell are discontinued and limited edition that many people collect. To say cosmetics are a collectors item may be far-fetched, but many people do save special edition collections. The harder an item is to find, usually will mean the price goes up, just like in anything else.
