It started with Woot. Interesting technological also-rans for cheap. The Big Lots for geeks.
So, where are the deals for musicians?
Musician's Friend now has their Stupid Deal of the Day. Today it is a box of six sets of D'Addario EXL110s with a pint glass for $20. Seeing as I'm hitting $6 or more per string set, I'd say this is a decent deal. Except I'm rocking much heavier strings right now. Still, tempting.
I normally dream to Musician's Friend. My music gear budget is minimal. I've actually ordered from them only once. But the stuff came quickly and was decent enough. (Never pay less than $20 for a harmonica, or you'll get cheap and uncomfortable thing you don't want in your mouth. I blame me more than MF.)
