Just out of surgery. Need a 8' 2x4 cut into 4 x 2' pieces - $1 (CORONA DEL MAR)

Hi.
If you have an old 2x4 sitting around, I need a freebie in CDM.
Just came out of major back surgery and I need to raise my main chair a bit (and make it more stable).
I can cut it, if need be.
Thank you! Need an 8' 2x4 cut into 4 x 2' pieces
