Guys servers/high bandwidth/tech support are not free and also they have lot of expenses, so don't ask him to increase price, if possible he will do, because he also want to survive and do business.
@ juno buddy,
rearrrange the PPD chart as Dynamic, Rates are fixed and Countries changes according to conversion.
eg:
i don't know how you calculate good conversion country and bad conversion country.
If good conversion (put in Group A)
If medium conversion (put in Group B)
If very conversion (put in Group C)
No conversion => Group D (pay $0.1/1000) or don't pay, we know bandwidth's are not free
so change chart every week say Sunday GMT 0.00 AM like that.
i am not forcing you to use this technique, decision is yours, it's just a idea so both you and us survive without problem.
If any body other have other idea share here, no offence :-=
