I REALLY like where you're going with this. Very creative! I love the shopping cart idea. However, I might also like to see some examples with less detail in the square. There might eventually be a black and white version of the logo that would be screen-printed on a shirt, so something with less detail might be good. But I REALLY like this! Bravo!
One more request: Can I see #41, but with the shopping cart just a little bit smaller (same sized square) and the ".com" to the right of the logo (as in #2)
Can I see two black and white versions of #64? One with a black outline as the box around the shopping cart and one without the outline (just the cart and the text) Also, just out of curiosity, what is the typeface you are using?
