I was going to buy a book entitled "I Never Promised You a Rose Garden" for my thesis on the site, but I cancelled it due to the price system mistake. I don't know whether it was programming error, or they mean to do it. As you can see the book price below
the crossed original price was Rp.165k and discounted become Rp.112.k. So, you save Rp.53k, pretty cheap, isn't it? I don't think so, because if you convert Rp.165k to US dollar, it's around $15, and Rp.112.k around $10, meanwhile in Amazon, it sells for $4,89 only. When, I clicked Beli (buy) button, the original price crossed again, but the total price didn't change it all! It supposed to be Rp.112k, and also in the sub-total the price didn't change.
Finally, I decided to save money rather than waste it.
