If you do WW online, you don't get anything in the mail, so deedeedee won't have a points slider. You basically get the eTools.
And yes, you can use the eTools to look up all of your points. If you look at eTools (log in to the WW site and click "Track POINTS values") then in the bottom left of the tracking screen, you will see a place to enter calories/fat/fiber. This does the same thing the slider does and calculates the POINTS for you. The good thing about the slider is that you can put it in your bag/purse and bring it with you on vacation (if you can't bring your computer) or to the grocery store, etc.
You could also buy one of the WW kits that come with a POINTS slider and use that as well. Its really thin and the height/width of maybe a paperback book. It "slides" so you can calculate your POINTS using the calorie/fat/fiber content of the food. You might be able to find a WW kit or POINTS slider on ebay for cheap too, so you might want to look there.
