300 of them for $100? Its on craigslist. I don't know if they have lids/rings. Most are quarts, some pints and half pints. Also don't know what brand they are yet. I emailed the seller. Just wondering if I should offer less or if that is a good deal.
Re: Is this a good deal? Canning Jars...
ditto. check for chips in the rims. If they come with rings that are in pristine shape, all the better. You would want to use new lids anyway though.
