Butter here (Fayetteville, NC, US) is all about the same price, around $2.75 for a standard sized package of 4 sticks. The store brand is a little cheaper, but contains carbs (added sugars?). I never liked the taste of the store brand, no butter flavor at all 
So for a long while, several years, I started buying the brand with the American aboriginal woman on the box (you know, the box we had fun with as kids
. It tasted ok. Even though the store brand was about 50 cents to a dollar cheaper, it was worth it.
Then I began hearing about Kerrygold on this forum and the podcasts. I had no idea what they were reffering to, because its name was used, but not what it was. THEN, one day in Walmart, I saw it, right next to the pretty girl on the box brand. Imported from Ireland it says, $2.88 cents?? I grabbed one to try. From then on I keep three bricks of it in my fridge. If you’ve never tried it, you are missing out.
(this comment is not a paid endorsement. If Kerrygold would like to pay me, I have no problem with that, and in fact, is encouraged).
