The big store that is in every town now (can't say their name) either does not carry anything or is always out of stock. If they ever have anything is stock, it is cheap junk that does not last. I got this cord thru amazon for a fraction of the price I usually pay for the junk at that big national store. This cord works perfectly and has lasted for months now. I also bought at the same time 2 other cheaper charger cords thru amazon that work perfectly. Since this one still works, I have the other two to fall back on when this one finally goes out. This is a great car charger, and it does not cost near as much as the junk you get at the local store--not to mention this is the Samsung brand charger verses their junk.
