Why oh why can't you put more than one promo code through per order? Even the lovely young man I spoke to on the phone couldn't override the system.
He said the parenting club was about the only instance that you could use more than one voucher at once anyway (I'm pretty sure that's not true), but now I'm going to have to lug myself into town to place the order in store, where they can put multiple vouchers through the till.
He said I could split the order up, but then I'd have to pay P&P as it would be less than the minimum amount for free delivery.
Why they can't do it on their online system beats me.
Gah.
