Knowledge Publications Steven Harris sell science books and other products Turtle Creek Pennsylvania

Made an order for molecular seives. After a month went my I did not receive order. I contacted company and was told shipping was going to cost more and they would follow up when they got the exact shipping quote. I never received the product, emails are not responded to and phone is dissconected.

I also requested to be removed from their mailing list. I was removed for a while but re-added. Had to request to be removed again.

Bottom line.  Doesn't ship product and  doesn't respond to emails. Avoid.
