IMPORTANT NOTE: To comply with Sephora's terms of use, items cannot be listed "for sale" or even for trade for Sephora or other gift cards. Please do not list "prices" either (which implies selling), but you can list approximate trade value.
Because a number of fake items have been sent in trades, it is strongly advised you provide photos of your higher-end items, including the labeling (you may be asked for it anyway) and list WHERE you purchased the item from. Fakes are readily available from less reputable sellers and can contain toxins! It is important to everyone to know where their cosmetics come from.
Please also be aware that some makeup products cannot be sanitized - please use caution in your trades. When in doubt, ask the community, it's a great resource! Used items you may wish to avoid are mascara, liquid eyeliner, lip glosses, and cream products.
Acquiring Items
Please use discretion with whom you enter into trades with. There is a summarized list of trusted traders here: http://community.sephora.com/t5/Off-Topic/List-of-Successful-Traders-January-2015/td-p/1852954 Protect yourself in your trades, ask questions (such as where an item was purchased), ask for additional photos (to show level of usage and/or labeling to prove authenticity).
If you don’t feel 100% comfortable doing a trade because someone is new, you can request they send their items first.
Communication
Please use the private message system on Beauty Talk and/or tag the user you are trying to get in touch with. Communication is key! You can tell a lot about a trade by how the communication goes. If you will be unavailable for any periods of time, please be up front, and if there are any issues with shipping please be up front about that as well.
Delivery
Having tracking and insurance on shipments goes a long way to figuring out where an item might be. The USPS puts anticipated delivery dates and tracking numbers right on the receipt. If there is any issue with an item you have sent out, please follow up with the carrier.
