I've done it before but my point is they don't really need it unless there are shortages, in which case they'll send a letter to me anyway. At least in the UK.marcooos said:Most places have spaces you just have to call up and ask. I'm lucky as the blood van is a 15 minute drive to another of my organisations sites so I can book it through work. But for real just email an search around an im sure you will find somewhere convenientEsotera said:They're usually pretty booked up, if you head in uncalled for an appointment in the UK they'll usually turn you away. I get the feeling they don't really have a shortage of people wanting to give blood most of the time, they just operate a just-in-time system in order to cut costs.
