My understanding is that:
- DTP paid through PayPal.
- She received the goods in person.

How she probably scammed the seller(s):
- After she received the goods in person, she filed a dispute/claim on PayPal to get her money back. She probably said that she never received the goods.
- PayPal asks the seller to provide proof of giving DTP the goods. Usually this is a tracking number. The seller cannot provide a tracking number (from CanadaPost or any other shipping company) because the transaction was in person.
- Since the seller does not have proof of giving DTP the goods, PayPal rules in DTP's favour and refunds the money back into her account.
- Once a PayPal dispute/claim is closed, it cannot be opened again.


So, if you are selling goods online and meeting in person:
Posting your items:
- Make sure you state that all sales are final.
- Describe the goods to the best of your ability. It's best to have a few pictures to show the style, condition, flaws, etc.
- Make sure you state that there are no try-ons. Try-ons are a waste of time for both the seller and the buyer, especially if the buyer does not want to buy the item. The buyer should know what size they are, especially if it is a popular brand (i.e. TNA). However, try-ons should be allowed for more expensive items ($100 to $200+).
The buyers:
- If there is a feedback system in place, only do transactions with buyers who have at least one positive feedback.
Payment:
- Do not accept PayPal if you are meeting in person.
Local pick-ups:
- Meet in a public area (i.e. a mall).
- Make sure you bring a friend when you meet someone in person.
- Do not meet with anyone who does not have a cell phone number.

If you are selling goods online and shipping:
Posting your items:
- Make sure you state that all sales are final.
- Describe the goods to the best of your ability. It's best to have a few pictures to show the style, condition, flaws, etc.
The buyers:
- If there is a feedback system in place, only do transactions with buyers who have at least one positive feedback.
Payment:
- Do not accept PayPal payments from a user with an unconfirmed address (to be confirmed, PayPal must call your house and speak with you).
- Do not accept credit card payments on PayPal.
- Do not accept personal cheques. If they bounce, you will be charged a fee by your bank. If you do choose to accept personal cheques, make sure you wait until they clear to ship the goods.
Shipping:
- Make sure you package the product carefully to avoid disputes/claims over damages.
- Make sure you ship by using CanadaPost parcels or PayPal shipping so that you have a shipping number in case of a dispute.
- If the goods are worth over $200.00, make sure you purchase insurance and have the goods signed for upon arrival.
