Is there any greater security or reliability of delivery in buying the hydroxychloroquine (USA to USA delivery) from buyivermectinstore.com compared to their hydroxychloroquine with unspecified routing?

The former would offer peace of mind, and that is the major benefit here. In practice, they may deliver to the U.S. from a U.S.-based storehouse to avoid complications from government scrutiny with a flood of packages going nationwide from overseas, and the possibility of raising concerns with Customs officials.
