Well it seems that not only AFTER SALES is bad, but also DURING SALES. haha.
Actually I think the reason why they do not put price tags is para makapagpatong sila sa price for their benefit.
Note that we can purchase as CASH or CREDIT basis (using citibank, hsbc, others). Even Cheques pwede bsata managers cheq, meron lang minimum amount I think.
Pag CASH they can put additional on top of the selling amount, sa kanila na yun. I think ganun yun. Kaya best siguro bumili using credit card, then cannot get their 'patong' immediately kase banks will pay the store and not the sales agent.
I think lang.
