Two recent (probably related) events that recently happened - FYI and as a warning.
I'm a new (10 day) PL seller - after 6 months of hard work sourcing my product in China. In launching my product- I used one of the launch platforms to sell highly discounted (80% off) products- about 10 a day. I set a limit of 2 products per order and have 2 color variations. One buyer used a single coupon to buy 4 units (2 each). Not what I had in mind, but ok. Yesterday, I found a second seller selling my PL product on Amazon at a discount of my standard Amazon price. That's a listing hijacking. Sent the buyer a Cease and Desist message (no response yet). 10 minutes later, same buyer filed for a refund from Amazon- saying the product was never received- Amazon naturally refunded it within a short time... Don't know how long I will wait for a Reimbursement from Amazon. Beware.
