This forum is run by macro mass. Largely a selective scammer. Moderators appear to be part of the scam.
Do not trust anything written in the macro mass thread. If you look closely, you can spot it is too good to be true.
Macromass will ask for payment to the below and will ship from the Philippines:-
First Name: SYED MUHAMMAD
Last Name: HAMZA
City: MULTAN
Zip: *******
Country: PAKISTAN
Do not do it. Months and months of excuses and bullsh*t. Often claims to have been hacked and restarts website.
Can't comment on other vendors listed. Re macro mass, I'd recommend heading to Pharmacy Reviewer forum and researching the many comments about the macro mass IOPlist scam.
