Garmin $50 Rebate
The offer is good for:
GPSMAP® 60C
GPSMAP 76C
eTrex® Legend C
GPSMAP 60CS
GPSMAP 76CS
eTrex Vista C
and is good from 3/1/05 - 7/5/05.
There do not seem to be any vendor restrictions, but it does say that it's not applicable to on-line auctions.
So, as near as I can tell, the GSMAP 60CS can be had for $332 + Shipping (getagps.com).
This is definately making me rethink my Explorist 600 pre-order.
