I'm considering Elixirs for my 5 string fretted basses. I've searched the forum and read a number of informative posts on these unique strings. My question is where is best place to get a low price on these strings? With an average discounted price of $50 a set for 5 strings, Elixers are not cheap. If you're paying less than $50 for a 5 string set, where are you buying them from? Thanks in advance for any tips!
