Poor, is this business still in business?
Received invite envelopes which were see-through which meant they were not fit for purpose. I phoned to request exchange but was informed have to pay 20% handling fee, plus delivery both ways (so 3 x £8 delivery). Bit of a difficult return policy which makes the express not so express. Delvery was speeedy though as a plus.
Ordered from France and delivery only took 2 working days. Envelopes good quality for the price.
