These are the very low end of eBay prices, and your bikeshop guy is getting a deal. Remember, he wants 'em for resale, not because he likes 'em. I'd put them back and wait for someday, because you'll have an endless struggle finding the right parts of the right vintage if you ever want to sell the bike (and it will be worth a breathtakingly lot more with the original parts on it).

The only thing that brings a better return than selling a bike one piece at a time is an "all original, excellent condition" bicycle that is sought by the collectors.
