Musicians Friend has this 4x12 cab on sale for $249.99 down from $999.99. With Cash Back it comes to $239.99 plus whatever shipping charges come out to for your area. They were around $40 for me. You can try price matching to Guitar Center for a bigger discount but YMMV. GC does matching plus 10% of the difference which would come out to $174.99.
