I agree that, absent any health problems when they're born of course, the age of the parents would concern me more than their close relation. Although accidental sibling matings are far from ideal, they're not the end of the world. However as others have said, genetic traits can be intensified in those close pairings (which is why linebreeding is a thing), so it is important to know what health or temperament problems you may be getting. (just for full disclosure, I'm basing this on my experiences with purebred horse breeding including sibling and parent/offspring matings, as I don't breed dogs)
My biggest hang-up in this particular situation is about the ethics of the owner of these dogs. I agree with those who said that an "oops" litter can happen even with the best management--it's unlikely if you're responsible, but one chewed-through barrier or irresponsible pet sitter or whatever is all it takes. I also don't think that it's inherently bad to let the bitch carry the puppies to term and then find good homes for them--as others have said, there may be reasons they want the dog intact, and from what I understand, abortion methods other than spay/abort are risky.
What concerns me is that you say the dogs are being offered at a discount, but not free. Even that isn't inherently a problem ("oops" puppies can still have value, after all), but I'd want to find out a lot about the owner and the circumstances of the conception before agreeing to pay. I would be concerned that, if this owner is some yahoo who doesn't manage the dogs right, paying them for the puppies may help convince them that they've hit on a great moneymaking plan.
I guess it depends a lot on how big the discount is, too. If their parents were sold for $3,000 apiece and the puppies are being offered for $2,000, I'd do a lot of research into the ethics of the people involved to make sure these are people I'm comfortable giving that kind of cash to. If the parents sold for $3,000 and the puppies are being offered for $300 in order to discourage people who can't really afford a dog or are purchasing on impulse, I'd feel a lot more comfortable assuming this is a true accident and the owner is just trying to get them a good home, if that makes any sense.
