... check the auction very carefully for clues.

I am planning a trip to Blackpool soon with some friends, and went on to ebay to search for promotional vouchers.I found one advertised as buy 2 wristbands and get 1 free.

I received it, and the vouchers seemed genuine, however the following week i got a voucher book from leisure vouchers with the exact same voucher in it. What the seller failed to tell me was to use this voucher, you must first purchase leisure vouchers, and use them as part payment when redeeming the vouchers. So yes i can use it, but i would have to buy some leisure vouchers first, then take them with me. Not as easy as just going to the ticket kiosk and handing over some cash and the voucher.

It is therefore, worth asking the seller if there are any other requirements to use the vouchers!

Hope this helps you save a few pennies!
