Toyota maintain a global price catalog of parts wherever they are officially selling it
That means if a part is 100 dollars in usa, it will be equal to pkr 160 x 100 + few % up and down to adjust for tarrif and freight in remote areas like maldives, mauritus or hawaii.
If some part is available for unbelievable rates its probably fake.
E.g. oldschool cruiser 80 genuine toyota balljoints are usd 200/piece, they sell for 70-75k a pair in Pakistan.
Ive been called moron/idiot/delusional because some person could find some balljoints in some unknown toyota package for 16k for both. Lol
Then same person says, because of Pakistan roads, they fail in a year, 80 series cruiser is an offroad truck. 
Remember that if its too good to be true, it probably is a fake. Ive seen tons and tons of “toyota jenyin” parts here in usa which were fakes.
Denso which is owned by Toyota itself sell aftermarket too, but there are millions of its fakes being sold too from aliexpress etc. or simply the box is local made to highest finish to fool customers.
Only buy from a reliable source. If the seller claims self import then ask for origin warehouse and cross check the part numbers with updated parts catalog entries, some part numbers are superseded and old NOS parts are sold in auction lots which “our importers” buy.
