I've seen these more in the NYC area than anywhere else, so I figured all you local FTers would know the answer...

Where can I buy a holder for my E-ZPass with suction cups (so it's transferable between my car and rental cars without having to hold it up to the window)? I've seen these online but the shipping costs are more than the cost of the holder itself, so if they're available in any brick and mortar store, I'd like to pick one up next time I'm in New York.

I've been dinged for missed tolls on the NJ Turnpike high-speed lanes before because my E-ZPass was not mounted correctly and thus not read...and the toll tags offered by car rental companies all have a surcharge, which I'd rather not pay since I have a no-fee Delaware E-ZPass to my name.

Thanks!
