One positive thing about Costco (although I don't do it much) is you can return anything and get your money back if you aren't pleased. Have only done this a few times. I don't know the ins and outs, but lately I've been wanting to buy a GPS for driving. A friend has an iPhone, and a road directions app that talks to her as she's driving, tells her when to make a turn, etc. I don't have a smartphone but figure a GPS would do the same thing, maybe a lot more. Costco has Garmin's and I saw 2-3 in the store a month ago. I just looked online and saw a better deal on the one I figured I favored.
In researching GPS's, people mention that the lifetime updates may not play out as you hope. IOW, a unit may not get updates after a certain time. The one I'm looking at (2595) has been out a couple of years I think and I don't want to have to buy another in 2-3 years. Someone said that's why they would want to get theirs from Costco because if it stopped working you could just bring it back and get your money back.
So, question is: If I buy from Costco online do I get the same return policy as if I buy in the store?
If you read the fine print on the Garmin unit, "Lifetime" is defined as the "lifetime" of the device and not yours. Last time I checked it was about 3 years from the date of release. You could argue that "stopped getting updates" after 2.5 / 3 years as working as intended and you returning it would be sketchy but whatever.
