Joewith my luck (and my conscience) -
I let the old lady know that I think the cards are worth $X amount not her low price.
I then buy them at $X amount, only to find out that they are worthless reprints and the old lady is in Reno spending my money.
I think if I am at a card show and see an uneducated (low) price... I buy without comment.
A garage sale may be different (because the person on the other side of the table does not sell cards for a living).
I do like to sleep at night... so I would say the best solution I could come up with would be to offer to sell those cards for her at a fair price (for a 20% fee resonable?), then offer them up here or on eBay.
I sleep well, make some money, and the old lady makes some money as well.
