Hmmmm indeed. They’re a different item to the normal gift voucher – they’re still available full price, but the conditions don’t seem to say you can’t use more than one at once…….
Whatever the case, I’ve stayed conservative and got a £50 and a £20, costing £51 with the £5 for spending £50 discount also applied. 3% quidco and 1% cashback from capital one means £70s worth has only cost me £49, which is pretty good really, and considering I’m after a new helmet and pedals in the new year will almost certainly be spent.
(I’ve also got my eye on a £700 bike but didn’t dare buy £560s worth in case they can only be used one at at time. Will kick myself if it turns out you can use them all at once……)
