Do they sell Gameboy Advance SP’s and if they do, how much?

Hi there! We do sell GBA SPs! Depending on the model, the 001 (front light) goes for around 75, while the 101 (back light) goes for around 100. They both come with the charger and a 90 day warranty

If you need a charger they also have them separately. I've personally picked up a few for the SPs I have.
