Hi there,
Regarding your request for info on DPDS, Check out google mate type in DPDS reviews! Not good at all. I ordered to have 5000 delivered for my wheelie bin cleaning company. I have a sticker on the leaflet that the customer should stick to the bin lid if they require service, i didnt get one! I always get at least one customer per 15 leaflets approx. Would be easier to get out and do them yourself at least you know they are out then!
Hope that helps!
