Signed up for the free sleeve, paid $1.00 shipping. Just looked at my bank statement before seeing numerous posts warning about this scam to find a $49.99 charge from Swingbits. Curious sbout what that charge was I called them only to learn that in the fine print of the free sleeve offer, you are signing up for a monthly subscription that continues unless cancelled within 7 days. They want the golf balls back if cancelled and offered a refund of 30% at first, after more bitching on my part they offered 50% refund. I bitched loud and long enough that they then finally offered me 100% refund and told me to keep the balls. DO NOT FALL FOR THIS SCAM!! BUYER BEWARE.....Numerous complaints about Swingbits scsm on Better Business Bureau website.
