Very helpful website for amazon.com shoppers
If you need a small item added to qualify for super saver shipping, you type in the amount you need (e.g. $2.01) and the site gives you a list of free shipping items at amazon that cost exactly that amount or a little more.
The only drawback I saw with that site is that it didn’t include most of the personal care items like soap that qualify for free shipping. If you still can’t find something at the slickfillers site try searching at amazon for toothpaste, soap, deodorant, gum, etc. and arrange by order of bestsellers (the free shipping items are usually the bestsellers). Just keep in mind that if you add a lot of these items to your wish list for future reference, like I did, amazon.com might tell you that you stink.
