Gail -
I picked up that same tip from them and it makes a big difference. Good on you for posting it!

Since my parents go to all the estate/yard sales in the area I had them looking for weights for me, but my wife and I were at a close out store (think Big Lots but a local store) and they had some for I think $2 so I bought one. It was a great investment. Just be sure you get the kind that are coated with plastic or silicone.
