So, earlier this month I picked up a set of JF324's for my new (to me) Mustang and absolutely loved the tone and tension. I think I paid around 70 bucks or so shipped. I liked them so much I decided to get some for my P which is currently wearing Chromes. A google search took me to Amazon where the best price was 44 dollars but the packaging looked different and they ship from UK. Shipping was only 6 bucks, so 53 with tax. Estimated shipping time was 3 weeks but they arrived today, one week after ordering. So what's the deal here? Are these ones in the blue pack lesser somehow? Old stock? They feel and sound the same. At any rate, my P has never sounded so good!
