BIC4ELECTRO
As per title, 6% off for all items under Electronics and it's subcategories, coupon valid for 2 orders.

If none of those are what you need, first time orders can get a 5% discount store wide using my recommender code bamzero
Just to be clear, this isn't all electronics, it only applies to items that you can find under the "electronics" tab on the BIC website. I just tried to purchase a car MP3 player, which comes under the "car accessories" tab, and the code doesn't work for that.
Here's an example of something the code does work for: a luggage scale with hook, that weighs up to 40kg:

Before coupon code it was US$3.49, after coupon code it was US$3.28. 6% lower, as promised.
