Really really nice work!
Actually TGB was sloppy and confused about the difference between a "Master Air Way Bill" and a "House Air Way Bill". One is the identifier for the whole delivery of the shipping company, the other one for each individual recipient. Both are visible on the parcels and they are labeled with n/24. The conclusion is obvious, I guess.
My
estimate was 187200 chips and guaranteed
less than 374400 chips. Order #3 with 200000 chips maybe?
