I don't post a lot, and I am still trying to learn how to navigate everything. I sold a product to a person on here, and I included shipping in the cost of the item. She purchased it on Friday evening, I purchased shipping cost online and the item was in transit. On Monday she filed a complaint with Paypal saying she hadn't received the item and demanded a full refund. this is really stressful for me, I am moving right now, and I didn't need this right now.
