If the pups aren't Kennel Club registered you have to be very careful. KC registration isn't foolproof, but it's the closest to a guarantee you can get. There are many possible reasons why the pups aren't registered. Maybe the bitch is too old/young. Maybe either the sire or dam aren't registered. Maybe they have non-breeding endorsements on their registration ... the list is lengthy.
Unregistered pups are worth a lot less money, so I wouldn't expect to pay more than about £200 for an unregistered Staffy, whatever the colour.
