I put it as 2 buds cas some sold for less than 2 buds or 2 buds and some sold for a tiny bit over. Maybe it should be like 1.88 buds to 2 buds so now i edited it

EDIT: Also the first seller for 2 buds hasnt sold in a month... and the quicksell for 2 buds in 3 weeks... so it should be lower for the solds and for that reason
