How I buy and sell on Backpackinglight.com
1. Look on the site to see what others are buying and selling the item for. Also check online retailers to see what the current market price is in case it happens to be on sale. Figure out how much shipping will cost. You may want to box it up, weigh it and go to usps.com and calculate how much it would cost to ship from your zip code to the furthest zip code from you. I use my zip as the origin and a Florida zip code (33030) as the destination to figure the most it would cost. Set your price.
2. Take a photo of your item (optional).
3. Create a new thread in Gear Swap: http://www.backpackinglight.com/cgi-bin/backpackinglight/forums/create_thread?forum=19
Write and format your product description and price and if that includes shipping (ie "$25 Shipped"). Indicate what kind of payment you will accept: PayPal, personal check, money order. Optionally, insert photos. Make sure you click "Watch this thread" when you view your post so you will be notified if anyone posts a message there.
4. Potential buyers will contact you by posting a message or sending you a PM.
5. Once you and the buyer agree on a price, the buyer will send payment via Paypal (or other agreed upon method). Only ship after you have verified that the payment is in your account.
PM Sent
People have the option of communicating with you in an open forum via posts or via PM. A "PM" is a personal message. When you set up your BPL account you can set up your email address in your profile so anyone can send you a message without you having to post it in a public forum. When someone wants to send you a PM, they click on your name in the post which pulls up your public profile page with a link, "Send a Personal Message (PM) to…" so they can compose a message. You will receive am email from BPL that includes their message and a link to reply through BPL. You can continue your message exchange through BPL or share your direct email address with the buyer. If someone is going to buy from you, you will eventually provide them with your email address anyway so they can send a payment through PayPal.
PayPal
There are also two types of payment methods available to buyers when making a payment: Personal and Standard.
There is no charge to the buyer for either method. For the seller, Personal Payments are free as long as the buyer funds the payment via a bank account or funds in their PayPal balance. For Standard payments, the fee to the seller is typically 2.9% of the amount plus $0.30. Buyers do not get buyer protection from Paypal when sending Personal Payments.
