I'm buying some fleetwood mac tickets for my mum's birthday and eBay seems to have a few available. Some of the auctions are for people with tickets in hand and other are simply people who have received order confirmations and are awaiting tickets. With the concert being in September, if I pay now, will I still be able to claim back the money through ebay/paypal if the tickets don't arrive? I know for some items, you have to raise a dispute within 30 days of buying the item (I think). Does this apply to all items?
