We found that the free shipping option (that is available for some items, namely the battery module assembly and/or PCB, but also others) was not put as the shipping cost by default. As such, some of you may have not ordered by fear of shipping costs - when actually the best shipping cost for you was zero !!
In other news, we are in the late stages of preparing the offer for a new (?) calculator, arriving in July, from HP of all producers !
