(Checking the numbers show 1k ped in the low end, but as I understand it it's a "common" part. An auction is prolly best with stuff like this but time is a factor too.)
gz and as prot DNA gatherer i must say that was good price for blood sample. There is one on auction now with 1050 ped BO and one bid at 400 peds for few days . Indeed it is common part like eyes, neck, toth and skins. Just MA set drop moments for various prices diferent and some seems more common than others. few AUction transactions set price.
As we dont know how many bloods it will take to make dna (maybe 100 even) that is realy good price from seeler point of wiev and bit to much from assembler point of wiev
