I ordered a battery charger for my computer Samsung R530 after looking in several stores of Le Havre (each time, not in stock, ... four days of waiting, model ... between 50 and 90 euros!) . I tried Amazon randomly controlled charger ... Monday night, ... arrived Wednesday late morning to relay point ... works perfectly ... for 35 euros delivery costs within one business day included ! Surprising ... and damage to the stores. This is not a review "can", I do not comment generally but I got used to read reviews on forums before buying, it is often instructive ... and sometimes discouraging!
