@christ1512 not impossible at all, in fact it doesn’t look like you are not a Member so you must have canceled it.
All you need to do is go to SideDeal.com/membership/cancel, scroll down and click the button that says “Cancel Membership”, confirm and done.
I was charged a fee of $5.43 on 4/14 from side deal. This is the membership for free shipping when item is purchased. Please check your system and cancel my membership.
@jsimonitsch you don’t seem to be a Member, if you need to contact support about a charge you would need to write in at SideDeal.com/support
It was easy to cancel. You just need to follow their instructions and it took about 10 seconds!
