I found this little nugget in Real Simple:
If you do only one thing this month
Text before you buy. Wondering whether that Lacoste Polo (or any store item) is a good deal? Send a text message to Google at 466453. Type “price” followed by the item name, such as “Lacoste Polo.” Within seconds, Google will send back prices at various retail outlets.
You mean we don’t even have to walk across the mall anymore?!
