You can exchange one4all gift cards for vouchers

Hi, just to let you all know if you get one of the dreaded one4all gift cards for Christmas, you can exchange it for a voucher at lots of shops

Thanks for @PigeonPigPie for this tip about 2 years ago! My SIL is addicted to these bloody things and I can now just exchange them for lovely JL vouchers.

I used the last one my child got for fuel. I entered £25:00 (voucher value) as the amount on the Sainsbury’s petrol pump, the pump allowed me to fill up to the exact amount and I used the voucher in the petrol station. Then gave my child £25 cash.

Its worth checking if Sainsbury’s fuel still accept them.

I hate them and used it immediately.
