During Happy Hour, use your mobile to buy an item on eBay.com.au and also pay for it with PayPal, and you'll receive 50% off the purchase price, including shipping cost, up to a maximum refund of $50.
Be among the first 5,000 to register between 12 noon Wednesday 22nd and 12 noon Thursday 23rd September AEST. Also, make sure you have both a PayPal email address and an eBay User ID. And if you miss out on Mobile Happy Hour you'll still go in the draw to win one of five $1,000 prizes* to be paid to your PayPal account.
Bought an item with my iPhone using the eBay app, pressed payment options and received a "NO YOU CAN'T PAY WITH YOUR PHONE" or something like that.
Contacted ebay live help an hour after happy hour when I could get onto a computer and was told
"Now, I have taken notes on your User ID and the item number. All you need to do is pay the item using a computer and I will be the one to credit the amount on your PayPal account. Expect that to be on Oct. 15."
So it was okay to pay after the happy hour not on your mobile. Just use live help first.
