Ups and Downs of Boys Clothing

What am I doing wrong here? DuckyBoy needs a raincoat. It's late June, I didn't think this would be such a problem.

Sears had ONE style. Wal-Mart and Target, nothing.

Not even any outerwear, like jackets, which makes me wonder if I'm really looking in the wrong place or something. I only saw a couple of sweatshirts.

Do I really need to buy this kind of stuff in April? How do I know what size he'll be in June, to shop in April?

I hate Internet clothes shopping, I can't tell the fit or feel, both of which matter to him.

On the up side, we just finished testing two t-shirts for the Soft line, and I am so excited for their launch (I think fall). DB liked the shirts so much he helped fill out the tester forms, which is saying a lot for a kid who avoids writing most of the time.
