Logo design for an innovative e-commerce website

C'est ce qu'une entreprise en/au(x) France recherchait pour leur logo design

We need a logo for an e-commerce website that we are currently developing named "Piwibi". On that website, we are selling trendy products with a discount that can reach -70%.
The products we are selling are in several categories : telephony, computers, tablets, cameras...

The final design can have the idea of "coin" which is a part of the concept and it should communicate the following ideas : bargain, savings and game.
The logo and the name of the website should fit together, not the name next to a picture.

For the colors, you have carte blanche, but the following should be avoided : green, black, yellow, orange. Voir plus
