Navionics+ - best place to buy?

Anyone know where the best place to buy the Navionics+?  Is there a coupon or something, those cards are expensive.

Navionics Platinum+ is on sale until April 30th for $30 off the normal price.  That's about the best deal I've seen on it.

It should be available at all dealers.  It's advertised on Navionics website.

Will not work with all FFs. Check before you buy. Navionics website.

Should have said the preprogrammed cards will not work with all FFs. But downloads are available.

Yup, I pulled up the compatibility chart.  I can only use Gold or Navaigon+.  Almost same price but since I have sonar, figured I help map the ocean and get the + version.
