Amazon currently has Ball Regular-Mouth Mason Jars with Lids and Bands, 12 ct priced at $8.09! This is the lowest price new these jars have been priced on Amazon!
I personally love the quart size for canning tomatoes and applesauce. I also have used this size to make homemade blackberry vodka (yum!). They are also the perfect size for storing items or crafting.
As a reminder, prices on Amazon can change at any time and without warning. If you’re interested, I’d jump quickly.
