I chose BecexTech because of their cheaper prices. It was my first time buying from them. On the wednesday I ordered a samsung galaxy s8 plus with a 2 GB SD card, and on the friday I received a 4 GB SD card in the mail, and on the monday my phone arrived, with an australian power adapter included for the battery charger. Thank you BecexTech for your quick delivery, I'm sure I'll seek your services in the future.
