trying to buy a new cannon sd 880 is digital camera at the lowest price i can find?

Yes, it is most likely a problem.

If it's more than $250 I'd be very careful...

There are lots of bait and switch sites out there. Broadway Photo, and it's little clones (really same store operating under different names that come and go quickly, because original name has too much bad things said about it online, so they hide under different labels) is the most notorious one, but there are many more.

Here's your main guide:

http://www.resellerratings.com/

Enter a store name or url into store ratings search box, and see the rating and read the comments. If you can't find a store or there are too few comments, none recent, beware. If store has low rating and many bad comments - run!

Normally, I would not trust any retailer who would claim they'd sell it for well below market price.

Reputable stores you can trust:

www.bhphoto.com - B&H: one of the most reputable of them all

www.amazon.com - Amazon.com is obviously a good source.

www.adorama.com - Another good store in New York.

www.beachcamera.com - This one is in NJ, also a good store, that usually has slight price edge over the above.

There are a few others I may have forgotten, but don't take my word, check resellerratings and only order if they have a good feedback, and a lot of it.

Good luck,

LEM.
