I hope this is allowed. 5.4 oz Haakaa with base and lid is on sale on Amazon right now. There is a 20% coupon from Amazon and a 35% discount code from the manufacturer. I highlighted them on the image. Amazon allowed me to use both for a combined discount of 55%. I paid ~$15 total including tax.

This is not meant as an advertisement, just a tip for other budget-conscious moms who have been considering getting one (like me)!
