For the most part excellent - one of the best sites I've reviewed on this forum. Clean, easy, nice layout - Good Job!

Some small nits for you:

Make the logo at the top link to the home page and add in alt text.

You use "buy" and "add to cart" I would standardize these.

There is an inconsistent spelling of Tzedakah Box on the page it appears on the h doesn't appear on other uses of the term.

On the checkout page the word checkout is all the way to the right it looks odd.

I would love soemone with your talent's comments on my site as well. I've reviewed over 25 sites with what I thought were professional and extensive reviews and not one person has reciprocted.
