I bought a tablet which did not work - right out of the box. I demanded a refund and mailed it back. Then their site disappeared! I thought my money was gone, but I files a dispute through paypal - and it worked! They refunded for the bad product though I was out the shipping costs (high).
I have ordered again with products that list "free shipping" because I now have credit on paypal to use/burn.
They have headphones for 1 cent with free shipping. If they are really bad to me again then I will order some individually - the shipping will far outstrip the 1 cent...
