Maybe no one else will think this is cool, but I didn't know you can comparison shop on your mobile phone. If you're in a store and can't access the internet to comparison shop, use this tip from Kiplinger Magazine:

1. Send a text message to 46645 (Google's number).

2. Type the letter "f" (for froogle/find) and then type in the product name. I put a space behind the "f".

You will receive a text message back from the comparison engine. EXAMPLE: I tried it for my Nikon 8800. I typed "f Nikon 8000". I got a text message back and saw that I can buy it for $649 at an online shop.

Anyway, it can help when you're out purchasing technology products or any other item that can be found on froogle.

Cool. This should save some money. I wonder if they've started this service in Europe as well.
