Apabila Anda pernah melihat situs yang menjual produk-produk baik itu elektronik maupun busana, biasanya disana ada sebuah kalkulator yang disediakan di situs tersebut. Karena dengan adanya kalkulator, pengunjung bisa langsung memperkirakan berapa jumlah uang yang akan dibelanjakan oleh calon pembeli. Nah bagi Anda yang suka berjualan di Blog jangan khawatir, karena kita juga bisa memasang kalkulator di Blog.
