If you'd like to see a 60-second preview of the video, you might be able to do so at Collage Video
. They offer about 700 fitness video previews so you can at least get an idea of what you're buying beforehand, and they give a really helpful breakdown of how the routine is set up, as they personally try every video before writing their review. There are also plenty of onsite customer reviews to read as well.
Then, I would suggest going to Froogle
and typing in the product name; you'll get the prices charged by all the online sources. I know you don't want to buy it online, but at least you'll get an idea of the various prices available, so you have some basis of comparison.
I'm about to start using the WATP DVD's myself; I've ordered the Walk Away the Pounds 1-3 mile; the 4-mile Challenge, and the Power Walk 3-mile/Power Firm DVD's. My 1-3 mile DVD does not include the bands or belt or balls she's offered over the years; I ordered separately a pair of 6 lb. (3 each) Ironwear Iron Hands instead. I've heard such good things about Leslie Sansone, I finally broke down and bought the ones I'd heard most strongly recommended.
I wish you every success with your new Leslie routine -- and good luck with your purchase!
