2 years back I sent a table to a customer for around £30. Firstly it got smashed. Secondly then came the good old "weight and size" issues. They wanted to charge me an extra £300+ saying I got the dimensions wrong etc. Luckily I payed through Paypal and cut them off from taking it. After lots of back and forth including them showing me a UPS invoice which was mostly blurred out, they disappeared. 2 YEARS LATER...they're BACK with emails demanding payment lol. No chance.
