I like the fact that you are creating a larger icon and downplaying the text. I need the letters WS in the graphic, maybe a bit of a play on a shopping cart (i wasn't crazy about the wheels). I ranked it number 1 because it is the only submission that is giving me what I've been asking for, a big graphic, little or no text.
Thanks for the comments. Here is my first variation... What do you thing of the general design? Do you like it? Should I work on another idea base? Colors are OK? Your feedback are very helpful.
