Before sending money to Medical And Lab Supplies (medical-and-lab-supplies.com), I'm trying to compare them with a couple other suppliers. Does their catalog list batch-specific COAs, and can you actually see those before checkout?
Prices—are they per unit, per vial, or per case, and do those include taxes, duties, and cold-chain fees or are those extra? For temp-sensitive stuff, what shipping details do they give: carrier, packaging, transit times, tracking?
Also where are they located, and where do orders ship from? That changes customs and delivery timelines for me.
And is there a stated return/replacement policy if something shows up out of spec or missing documentation? Not trying to trash them, just want the basics before I commit.
