corporations are always tempted to do this, which is why we have anti-trust type laws
(but we use some Teva products and they are VERY reasonably-priced, indeed we’ve commented on this fact...they provide a lot of generic, off-patent medicines and so they specialize in these lower-cost products)
I just paid $1.44 for a Teva Z pack that my doc prescribed. Cheap. Manufactured in Croatia. Thankfully it worked.
