It wasn't long before the seller, who claims to have attended Cashmere High School in Christchurch, messaged Low saying she had the exact saddle for sale.
Through messages to each other it was arranged that Low pay into an account and the saddle would then be sent north by a trucking company.
The seller said she needed the money saying: "If you're happy to purchase with guarantee of refund if not happy/not the right fit that would be fantastic."
She added: "No worries with you holding on to it at all."
Low sent a screen shot as evidence she had paid the money.
The seller responded: "Thank you so much for a nice easy trade."
However, suspicions were aroused when Low saw the exact photo of the saddle for sale on another Facebook page.
When Low queried the seller about it she was suddenly blocked by the seller and unable to contact her.
Low went to the Whangārei police station and reported the incident. She also went back on the Facebook page and warned others of the dubious seller.
"Looking back on it the saddle was cheap for what it was. But I've bought plenty of items like halters and bridles and they have been honest people," said Low.
She said in future she would get a phone number to talk to people on the phone, and while it was not always going to be foolproof, it would give her a better idea of the person. Even video calling the seller so you could see them with the item would be good, she said.
Getting proof of the seller's physical address would also help if things went wrong.
