Train (any) Voucher worth £285 for only for £250 one year valid +

I was given a full refund in vouchers by eastcoast for the train delay. They have to be used within a year and I am not a frequent traveller. They are still valid for 11 months and 2 weeks. You will save 35 if you buy all of them, total of 285 worth. I am just asking 250 for all of them. Thank you!
