Here is an amazon link that comes with the wet blade and lid https://smile.amazon.com/Vitamix-15842-Container-32-oz/dp/B00194ETQC

Note, the tamper for the 64oz jar won't fit in the 32oz lid b/c it's too long and can hit the blades. The tamper for the 32oz jar is https://smile.amazon.com/Vitamix-15033-Mini-Tamper/dp/B00B32N4PC

Note, you can get these cheaper on places like eBay but if you're not comfortable with eBay you can use the Vitamix or Amazon links. BTW, Amazon isn't much cheaper than directly from Vitamix (5 cents). I don't know if there is a benefit of ordering from Vitamix or not e.g. better warranty or anything.
