1.) I like Stamps.com. I think it's worth the monthly fee, even in these economic times. Especially for international shipping.
2.) Frantz makes the best bead release. Period. Except, don't water it down too much, that is bad news.
3.) Alway watch out for striking red rods mixed in with amber rods. Most people would notice right away... but it took me a whole rod for it to click that something wasn't right.
