I havent really posted here before so hope im doing it right. I was looking to buy a 16" pool ball for a bday present and noticed amazon is running a promotion where if you buy a large led you get a 10 pack of pumpkin leds (34.99) and 10 pack of mini ball leds (106.99) for free. Theres a coupon code too which brings the price down to 72,49 for all 3!! thats cheaper than the ball alone.
Ive bought these before and this is an amazing deal especially if you sell the free stuff. The promotions are stack-able.
they also seem to have 3 promotions for free if you buy the 12" ball.
UPDATE: It seems you can return the promotional items. This will bring the price down to 24.44 for a 16" ball.
